We bring down the first number inside the box, 2, unchanged.
_______
-1| 2 7 5
_______
2
Now we multiply that 2 by the number outside, -1:
_______
-1| 2 7 5
-2
2
Now we add the two numbers in the middle column:
________
-1| 2 7 5
-2
2 5
Multiply the 5 we brought down by the -1:
________
-1| 2 7 5
-2 -5
2 5
Add the numbers in the last column:
________
-1| 2 7 5
-2 -5
2 5 0
The 3 numbers under the box represent the coefficients of x² and x, as well as the constant. When we finish, we no longer have an x², but start at the next level down, which would be x. 2 would be the coefficient of x and 5 would be the constant, with 0 remainder.

A triangular playground has angles with measures in ratio 8: 3: 9 what is the measure of the smallest angle
Answers
20x = 180
x = 180/20
x = 9
The smallest angle is: 3×9 = 27 degrees
Note: 180 degrees is the sum of angles in a triangle
Answer:
The measure of the smallest angle is 27°
Step-by-step explanation:
The triangle has angles with measure ratio 8:3:9, so the sizes of the angles are going to change depends on the ratio.
Let’s name the common value as “α”.
Basing on the angle-sum property, we already know that the sum of the angle in a triangle is 180°.
The measure of each one are:
8α, 3α, 9α
The sum of these is 180°.
Then,
8α + 3α + 9α = 180°
Let’s sum similar values:
20α =180°
α= 180°/20
α= 9
Replacing values, we going to find the measure of each angle:
8(9) = 72°
3(9) = 27°
9(9) = 81°
The measure of the smallest angle is 27°

factor each polynomial 9x-6 a.9(x-6) b.3(3x-2) c.6(3x-1) d.3x
Answers
The correct answer is b) 3(3x - 2)
In order to factor this, you have to find the greatest common factor of 9x and 6. Since 6 does not have an x in it, we cannot pull out an x. Instead we have to look for the biggest whole number that goes into 9 and 6, which is 3.
Next, to take the 3 out, we need to divide each term by 3.
9x/3 = 3x
-6/3 = -2
So the 3 comes out and the results above go together in the parenthesis.
3(3x - 2)
[tex] 9x-6=3(3x-2)\implies\text{B} [/tex]

During a basketball game, the East Middle School Tigers scored 42 points from two-point baskets. How many two-point baskets did they make?
84
14
21
42
Answers
Answer:
21 two point basket.
Step-by-step explanation:
It is given that During a basketball game, the East Middle School Tigers scored 42 points from two-point baskets. It means
Total score = 42 points
Score for each basket = 2 point
Let total number of two-point baskets be x. So,
Total score = 2x points.
[tex]2x=42[/tex]
Divide both sides by 2.
[tex]\dfrac{2x}{2}=\dfrac{42}{2}[/tex]
[tex]x=21[/tex]
Hence, they make 21 two point basket.

Answers
B. 320 seconds or 5 minutes and 20 seconds
C. 27687 steps
There are 5280 feet per mile. In A, 3 strides per second at 5 feet gives us 15 ft per second. 5280/15 = 352 seconds. In B, 3 strides per second at 5.5 feet gives us 16.5 feet per second. 5280/16.5 = 320 seconds. In C, we calculate the total feet to divide by 5 per step. multiply 26 miles by 5280 to get feet per mile and multiply 385 by 3 to get the feet per yard. Add them together. then divide by 5. 26(5280) + 385(3) =138435. 138435/5 = 27687 steps

you owe $1,945.61 on a credit card that has an 11.2% APR. the minimum payment due is $156.00. you decide to pay $300.00. how much do you save in interest by paying more than the minimum, assuming you make both payments at the beginning of the month?
$,
Answers
Answer:
$1.344
Step-by-step explanation:
APR represents annual percentage rate, and it specifies the amount of interest that would accrue on a loan over a specified period.
Extra amount paid = $300 - $156 = $144
Annual interest that would have been paid on the extra $144 = $144 * 11.2/100= $16.128
this amount on monthly basis is $16.128/12 = $1.344

What is the simplest form of root 3.025
Answers
Explanation:
1) By convention if you do not mention the index of the root it is square root.
2) By definition the square root of a number x is the numberwhose square is the original number, i.e.
√3025 = 55 because 55^2 = 3025.
3) 3025 is a perfect square because it is the square of a whole numbe.
4) It is easy to find the square root of a perfect square, but if the number is not easily reknownm as a perfect square you will have to probe with several numbers until finding the square root.
For example, you might easily realize that 50^2 is 2500, and that 60^2 is 3600, so you start testing numbers greater thatn 50 and less than 60 until you get 55^2 = 3025.
5) How can you simplify a radical? If you know the properties of radicals you can simplify a radical easily.
You start by decomposing 3025 into its prime factors.
That will result into:
[tex]3025 =5^2{11}^2[/tex]
Then, by radical properties:
[tex] \sqrt{5^2{11}^2} = \sqrt{5^2} \sqrt{{11}^2} =(5)(11)=(55)[/tex]
So, the simplest form of √3025 is 55.

Answers
The strategy for expressions with variables is still to factor out the greatest term.
For [tex]10x^4y^3-5x^3y^2+20x^2y[/tex], we look for the largest factor in each term.
For [tex]10x^4y^3[/tex], the largest factors are [tex]x^4[/tex] and [tex]y^3[/tex]. We'll come back to the coefficients in a minute.
For [tex]-5x^3y^2[/tex], the largest factors are [tex]x^3[/tex] and [tex]y^2[/tex]. Now, looking back to the previous term and also considering the coefficients, the largest factor of the two is [tex]5x^3y^2[/tex]. You could rewrite the first term as [tex](5x^3y^2)(2xy)[/tex] and the second term as [tex]-1(5x^3y^2)[/tex].
Now, we consider the last term, [tex]20x^2y[/tex]. The largest factor common to the two other terms is [tex]5x^2y[/tex].
And that's our final answer for the GCF (answer D).
The GCF of the given expression is:
[tex]5x^2y[/tex]
Step-by-step explanation:The GCF ( greatest common factor ) is the greatest divisor which divides all the terms completely.
Here we have the expression as:
[tex]10x^4y^3-5x^3y^2+20x^2y[/tex]
Here we see that the factors of the first term are:
[tex]10x^4y^3=2\times 5\times x\times x\times x\times x\times y\times y\times y[/tex]
The factor of the second term is:
[tex]-5x^3y^2=-1\times 5\times x\times x\times x\times y\times y[/tex]
and the factor of the third term is:
[tex]20x^2y=2\times 2\times 5\times x\times x\times y[/tex]
i.e. the factor which is common to all the three terms are:
[tex]5\times x\times x\times y=5x^2y[/tex]
Hence, the GCF is: [tex]5x^2y[/tex]
Someone please help me find x and y for problems #19 and 20!!! Please explain if you can
Answers
19) you have 40 for one leg, 10 for another leg and 50 for a hypotenuse. To find x, the altitude, you need to set up the ratio, 10/x=x/40. You can multiply x by both sides. 10=x^2/40. You can also multiply 40 by both sides. 400=x^2. Square root both sides. 20=x. You now have one variable, let's solve for y now :0. Using the biggest triangle, we have 50 as the hypotenuse. You can use the Pythagorean Theorem to help you out. We first need to find the value of one of the legs, so 40^2+20^2=c^2. This gets me to 2000=c^2. Take the square root of both sides. I get c=44.72 (be aware that I'll always round to the nearest hundredth for every ANSWER! It's a bit more accurate). Now to find the leg of the biggest triangle. y^2+44.72^2=50^2 which is y^2+1999.8784=2500. Subtract 1999.8784 from both sides to get y^2=500.1216. Take the sqrt or square root of both sides. (It's rounded) y=22.36. That's question 19 for ya.
20) Look at this now! Doesn't it look familiar? Let's start with y. Start with the ratio '21/y=y/4'. Use my ways from before to get (you can pretend the same thing is happening from prob. 19)), '21=(y^2)/4' '84=y^2' 'y=9.17'. That's y, now x. Let's find the leg of the big triangle first. PYTHAGOREAN THEOREM!!! 21^2+9.17^2=c^2, 441+84.0889=c^2,
c^2=525.0889, c=22.91. We can finally figure out x. 22.91^2+x^2=25^2, 524.8681+x^2=625, x^2=100.1319, x=10.01.

Which statement best describes how to determine whether f(x) = x3 + 5x + 1 is an even function?
Answers
→ Even: f(x) = f(-x) → Odd: -f(x) = f(-x)
If -f(x), then -f(x) = -x³ + 5x If x = -x, then f(-x) = -x³ + 5x
Since -f(x) = f(x), the function is therefore odd.
The answer is B) Determine whether (–x)^3 + 5(–x) + 1 is equivalent to x^3 + 5x + 1

Answers
The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.
Total distance traveled = 123 miles + 4 miles + 191 miles = 318 miles
Total time taken = 2 hours + 15 minutes + [tex] 3\frac{3}{4} [/tex] hours
= 2 hours + [tex] \frac{15}{60} [/tex] hour + [tex] \frac{15}{4} [/tex] hours
= [tex] 2+\frac{1}{4}+\frac{15}{4} [/tex] hours
=[tex] 2+\frac{16}{4} [/tex] hours
= 6 hours
Average speed = Total distance [tex] \div [/tex] Total time
= [tex] \frac{318}{6} [/tex] mile per hour
= 53 mile per hour.

What happens to the surface area of a rectangular prism when each of the dimensions is doubled? (1 point) i?
Answers
Final answer:
The surface area of a rectangular prism increases by four times when each of the dimensions is doubled because surface area scales in proportion to the square of the linear dimensions.
Explanation:
When the dimensions of a rectangular prism are doubled, the surface area of the prism increases by a factor of four. This is because the surface area is proportional to the square of the linear dimensions. If the length, width, and height of the prism are doubled, the new surface area (A') compared to the original surface area (A) is calculated as follows:
A' = 2l × 2w + 2l × 2h + 2w × 2h
A' = 4(lw + lh + wh)
A' = 4A
Thus, if each dimension is doubled, the surface area increases by four times.
