NEED HELP!!!!!!!!
George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30-x) feet. The diagram below shows his plan.

Recall the formulas for area and perimeter: A = lw and P = 2l + 2w.




How many feet of fencing will George need for the dog run?
22 feet
68 feet
76 feet
82 feet

2x+3=5

Subtract 3 both sides

2x=5-3

Simplify

2x=2

Divide 2 each side

X= 2/2

Evaluate

X=1

Now second part

2x+3=-5

2x=-5-3

2x= -8

X=-8/2

X=-4

So x= 1,-4

You had to used least common multiple of 6 and 3.

Prime factorization of 6: 1, 2, 3, 6

3*2=6

Prime factorization of 3: 1, 3

1*3=3

Then multiply by the number

3*2=6

You can also multiply by each numerator by the same amount needed to multiply its corresponding denominator to turn it into the least common multiple is 6.

Then you had to used 4/3 multiply by the denominator and numerator by 2.

[tex]\frac{4}{3}=\frac{4*2}{3*2}=\frac{8}{6}[/tex]

[tex]\frac{29}{6}-\frac{8}{6}[/tex]

Since the denominators are equal, it combine by the fractions.

[tex]\frac{29-8}{6}[/tex]

Then you can subtract by the numbers.

Answer:

Insert a number into the x,

the middle column, you just substitute,

and the last column, you enter what x and y is.

Step-by-step explanation:

For example,

if x was 5, I would write 5 under the column,

under the y=2x+5 column, you would write y=2*5+5,

and under the last column you would write (5, 15)

Answer:

Step-by-step explanation:

9 *10= 90 feet

90+ 46= 136 square feet

f(5) = 4(5) - 11

f(5) = 20 - 11

f(5) = 9

The answer is 9 :)

Please give BRAINIEST :)

Thanks

By assigning the value of X to the function, we have:

f( x ) = 4 x - 11

f ( 5 ) = 4 * 5 - 11

f ( 5 ) = 20 - 11

f(5 ) =  9

therefore f ( 5 ) = 9

Answer:

x=2

Step-by-step explanation:

To solve this, you must isolate x. To do this, divide both sides by 425 because that is what x is being multiplied by (and dividing is its opposite). Then, you get the answer, x=2.

[tex]x=\sqrt{3}-1[/tex] or [tex]x=-\sqrt{3}-1[/tex]

EXPLANATION

To complete the square for [tex]x^2+2x-2=0[/tex].

We rewrite the equation to get

[tex]x^2+2x=2[/tex].

We now add [tex](1)^2[/tex] to both sides to get

[tex]x^2+2x+1^2=2+1^2[/tex].

The expression on the Left Hand Side of the equation is a perfect square.

So our equation becomes

[tex](x+1)^2=2+1[/tex]

This gives us,

[tex](x+1)^2=3[/tex]

We take square root of both sides to obtain,

[tex]x+1=\pm \sqrt{3}[/tex]

[tex]x=-1\pm \sqrt{3}[/tex]

We split the [tex]\pm[/tex] to obtain,

[tex]x=\sqrt{3}-1[/tex]

or

[tex]x=-\sqrt{3}-1[/tex]

Answer:

x = √3 - 1 and x = -√3 - 1

Step-by-step explanation:

x^2  +2x - 2 = 0

To solve this equation, keep the variables on one side and constants on the other

x^2 + 2x = 2

Now to complete the square, divide the coefficient of x by 2:

2x ---> coefficient of x is 2

so 2/2 = 1

Now add the square of 1 to both the sides of the equation:

x^2 + 2x + (1)^2 = 2 + (1)^2

which makes it

(x + 1)^2 = 3

To solve it, take square root of both sides which gives

x = √3 - 1 and x = -√3 - 1

it is true!!!! hope this helps

In this flowchart proof, we utilised the Corresponding Angles Postulate to conclude that line c is parallel to line d. Given that line a is parallel to line b, and angle 7 is congruent to angle 10, we can say that corresponding angles on line c and line d are also congruent, hence proving line c is parallel to line d.

For this flowchart proof, we will use the idea of corresponding angles and the postulate that if a transversal intersects two lines and the corresponding angles are congruent, then the lines are parallel.

Final answer:

The domain of the function f(x)=5ˣ-3+1 is all real numbers (-∞, +∞), and the range is all real numbers greater than -2 (-2, +∞).

Explanation:

For the given function f(x) = 5ˣ - 3 + 1, the domain and range can be determined by understanding the behavior of the function's formula. The domain refers to all possible x-values that can be input into the function, and the range refers to all possible y-values that the function can output.

The domain of any exponential function like 5ˣ is all real numbers because you can raise 5 to any power, whether it's positive, negative, or zero. Therefore, the domain of f(x) is (-∞, +∞).

To find the range of the function, we look at the output values. Since exponential functions grow without bound as x increases and approach zero as x decreases (but never actually reaches zero), 5^x will do the same. When we subtract 3 and then add 1, we're simply moving the graph down by 2 units. Thus, where the original function 5ˣ would never be less than 0, after the transformation, the function will never be less than -2. So, the range of f(x) is (-2, +∞).

B. 0.44

C. 0.1

D. 2.75

Answer: a) 0.370 b) 0.440 c) 0.1 d) 2.75

Step-by-step explanation:

Since we have given that

a. 0.370, 0.307, 0.037, 0.3007

First we write it in the ascending order :

0.037<0.3007<0.307<0.370

So, the largest decimal = 0.370

b. 0.404, 0.044, 0.44

We write it in ascending order :

0.044<0.404<0.440

So, the largest decimal = 0.440

c. 0.05, 0.049, 0.009, 0.1

Ascending order :

0.009<0.049<0.05<0.1

So, the largest decimal = 0.1

d. 2.7, 2.5, 2.75

Ascending order :

2.5<2.7<2.75

So, the largest decimal = 2.75

I would say that the answer that best describes the distributive property is "a property of the real numbers that states that the order in which numbers are added or multiplied does not change the value". Distributive property says that when you have a(b+c), you can add b and c together and then multiply by a or multiply b and c by a separately and then add them together after. It does not matter what order you choose to add and multiply in.

I hope this helps :)

The addition property of equality is the idea we can add some number to both sides of an equation. You must add the same number to both sides to keep things balanced.

It's asking "what number can we add to both sides of this equation so that we isolate x?"

Think of 20+x as x+20. We can rearrange terms since adding in any order doesn't matter (eg: 2+3 = 3+2 = 5)

So we really have this equation: x+20 = 25

We can add -20 to both sides to cancel out the +20 on the left side

x+20 = 25

x+20+(-20) = 25+(-20) ...... add -20 to both sides

x = 5

This is the exact same as subtracting 20 from both sides. So 5 will go where x is, meaning that 20+x = 20+5 = 25

-98-31 can also be written as

(-98) + (-31)

We know 98+31=129

Therefore -129

The student's question about '-98 - 31' refers to simple subtraction, not the additive inverse property. Subtracting 31 from -98 provides the answer, -129.

The student asked how to solve the expression -98 - 31 using the additive inverse property. The additive inverse property states that: for any number 'a', there is a number '-a' such that: 'a + -a = 0'. Applying this property, if you were to add 98 to -98, it would give 0. However, the question asks for -98 - 31. This doesn't require the additive inverse property, but simple subtraction. Subtract 31 from -98 to get -129.

1 because any number times 1 equals itself.

Example: 3 times 1 = 3

Final answer:

The factor is 1. When you multiply any number by 1, the product is always equal to the number itself.

Explanation:

The factor is 1.

When you multiply any number by 1, the product is always equal to the number itself.

This is because multiplying by 1 does not change the value of the quantity. For example, if you multiply 5 by 1, the product is 5.

In algebra, the concept of multiplying by 1 is often used to simplify equations or expressions.

By multiplying both sides of an equation or an expression by 1, the equality is preserved, and it allows us to rearrange the terms or cancel out certain factors.

The answer would be 230 2/3, because to get the perimeter you have to add all the sides together, 60 5/6 + 59 1/3 + 56 1/6 + 54 1/3 = 230 2/3

The correct perimeter of the figure is 230 2/3 ft. Here option C is correct.

The perimeter of the figure is the sum of the lengths of all its sides. To find the perimeter, we need to add the fractions given for each side.

We can do this by finding the common denominator and then adding the numerators. The common denominator for 3, 6 and 9 is 18. So, we have:

54 1/3 ft = 54 + 1/3 ft = 54 + 6/18 ft = 54 6/18 ft

56 1/6 ft = 56 + 1/6 ft = 56 + 3/18 ft = 56 3/18 ft

59 1/3 ft = 59 + 1/3 ft = 59 + 6/18 ft = 59 6/18 ft

60 5/6 ft = 60 + 5/6 ft = 60 + 15/18 ft = 60 15/18 ft

Now, we can add the fractions and simplify:

54 6/18 ft + 56 3/18 ft + 59 6/18 ft + 60 15/18 ft

= (54 + 56 + 59 + 60) + (6 + 3 + 6 + 15)/18 ft

= 229 + 30/18 ft

= 229 + 1 12/18 ft

= 229 + 1 2/3 ft

= 230 2/3 ft

Therefore, the perimeter of the figure is 230 2/3 ft. Here option C is correct.
