Answer:
Uhh? You can't factor this!
Step-by-step explanation:
So.. we see that the last term, the constant, (the +5) is positive, which means the two terms (the a and b on the (x+a)(x+b) must be either both positive or both negative).
We try positive, and we end up with
(x+1)(x+5)
x^2 + x + 5x + 5
x^2 + 6x + 5
which is not what we want!
We try negative, and we end up with
(x-1)(x-5)
x^2 -x -5x +5
x^2 -6x +5
which is also not what we want!
This isn't factorable!
You can always complete the square or utilize the quadratic equation, but you can't factor it.

Hawaii (12° F)
-60South Dakota (-58° F)
Enter the difference, in degrees, between the record low temperatures
Hawaii and South Dakota.
Final answer:
The difference in degrees between the record-low temperatures of Hawaii and South Dakota is 70°F.
Explanation:
The difference in degrees between the record-low temperatures of Hawaii and South Dakota can be found by subtracting the temperature of South Dakota from the temperature of Hawaii.
Hawaii has a record low temperature of 12°F and South Dakota has a record low temperature of -58°F.
Therefore, the difference in degrees between the two record-low temperatures is:
(12°F) - (-58°F)
= 12°F + 58°F
= 70°F.

The number 6.82245628434 rounded to 5 decimal places is 6.82245.
Explanation:To round the number 6.82245628434 to 5 decimal places, you should consider the 6th digit beyond the decimal point. In this case, the 6th digit is number 5, and the 5th digit is 2 that is even. Because the digit following the decimal place you are rounding to (5th place, the digit is 2) is exactly 5 and preceding digit is even, you don't round up the preceding digit. So, when you round 6.82245628434 to 5 decimal places, you get 6.82245.

A pyramid-shaped roof has a slant height of 16 ft and its square base is 40 ft wide. How much roofing material is needed to
cover the roof?
Answer:
1280ft²
Step-by-step explanation:
To find the total surface area of a square pyramid, we find the area of the square base and add it to the area of the four triangular faces.
The area of the square base is
[tex] {40}^{2} = 1600 {ft}^{2} [/tex]
The area of the four triangular faces is
[tex] = 4 \times \frac{1}{2} \times 40 \times 16 = 1280 {ft}^{2} [/tex]
In the context of this problem , the base will not be roofed, therefore the 1280 ft² of material is needed to cover the roof

Find the equation using the graph and table of values.
Answer:
[tex]y=-1x+1[/tex]
Step-by-step explanation:
To find the equation, you have to know the equation 'format' which is [tex]y=mx+b[/tex]
mx is the slope
b is the y-intercept
The slope is -1 because it goes down 1 and right 1 [tex]\frac{rise}{run}[/tex]
The y-intercept is 1 because that is where the line touches the y-axis.
So, if we plug it in, it will look like:
y = -1x + 1 which can also be written as y = -x + 1

a rectangle has an are of 240 square centimeters. The height of the rectangle is 24 centimeters. What is length of its base?
Answer:
The length is 10 cm
Step-by-step explanation:
The area of a rectangle is found by
A = l*w
240 = 24*l
Divide each side by 24
240/24 = 24l/24
10 =l
The length is 10 cm
The common difference ,d in an arithmetic sequence whose fourth term is 16 and whose seventh therm is 31
Answer: d=5
Step-by-step explanation:
Arithmetic progression
An=a1+d(n-1)
An= nth term
A1= first term
D= common difference
N= nth position
We are given the 4th and 7th terms
For 4th term,n=4
A4=a1+d(4-1)
A4= 16
16= a1+d(4-1)
16= a1+3d........equation 1
For the 7th term,n=7
A7=a1+d(7-1)
A7= 31
31=a1+6d......equation 2
Bring them together
16=a1+3d
31=a1+6d
Subtract equation 1 from 2
So we have
15=3d
D=15/3
D=5
Therefore, the common difference is 5

What is the distance between (-6,4) and (-8, 6)?
Answer:
[tex]\sqrt{8}=2\sqrt{2}[/tex]
Step-by-step explanation:
by using well known formula, distance on XOY plane
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=\sqrt{(-8-(-6))^2+(6-4)^2}
\\=\sqrt{(-2)^2+(2)^2}[/tex]
The distance between the points (-6,4) and (-8, 6) can be found using the distance formula derived from the Pythagorean Theorem. After substituting and simplifying, we find the distance to be sqrt[8] or about 2.83 when rounded to two decimal places.
To find the distance between two points, we use the distance formula derived from the Pythagorean Theorem: d = sqrt[(x2 - x1)² + (y2 - y1)²].
Here, we are trying to find the distance between points (-6,4) and (-8, 6). We assign (-6,4) to (x1, y1) and (-8,6) to (x2, y2).
So, substituting into our formula we get: d = sqrt[(-8 - (-6))² + (6 - 4)²] = sqrt[(2)^2 + (2)^2] = sqrt[4 + 4] = sqrt[8] or about 2.83 when rounded to two decimal places.

44-12=32
Answer:

Answer: Recess was 32 minutes long.
A windshield wiper blade turns through an angle of 135°. The bottom of the blade traces an arc with a 5-inch radius. The top of the blade traces an arc with a 22-inch radius. To the nearest inch, how much longer is the top arc than the bottom arc? Round to the nearest whole number.
The upper arc is longer than the lower arc by inches.
Step-by-step explanation:
Since both the arcs are made by the same wiper blade, hence the angle of the arc would be the same.
The radius of upper arc= 22 inch
The radius of the lower arc= 5 inch
Angle made by the arc= 135°
We know that length of the arc= (angle made/360)*2πr
Where r is the radius of the arc
The difference in the arc length has been due to the difference in radius of the arcs.
Hence, the difference in the radius would be equal to the difference in arc length.
Difference in wiper radius= 22-5= 17 inch
Putting the values together
arc length= (135/360)*2*3.14*17
arc length= 40.035
The difference in arc length=40 inches (rounded off to the nearest whole number)
