Answer: 2,955 feet squared.

Step-by-step explanation: The area is the width times the height. The area of the whole room is 64*48=3,072 and when excluding the area of the carpet which is 9*13=117 you get 3,072-117=2,955 feet squared.

What is the square root of 96 Follow my new brainly at: fol

Ugo [173]

Answer:

4√6

Step-by-step explanation:

For right now, I will assume that the "Follow my new brainly at.." part is irrelevant.

Anyways, to find the square root of a number, usually the best way is to find its prime factorization first:

96 : $2^5\cdot \:3$

We can rewrite that as:

$\sqrt{2^4\cdot \:2\cdot \:3}$

Simplify!

$2^{\frac{4}{2}}\sqrt{2\cdot \:3}$

Since $2^{\frac{4}{2}}\sqrt{2\cdot \:3}$ is the same thing as $4\sqrt{6}$ , that is our answer.

Thusly, as seen above, the answer is $\boxed{4\sqrt{6}}$ .

Hope this helps! ((;

Answer:

(-4,-2)

x=-4

y=-2

Step-by-step explanation:

-3x-4y=20

3(x-10y=16)=3x-30y=48

The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.

-3x-4y=20

+ 3x-30y=48

-34y=68

Divide -34 from both sides.

y=-2

To find x you need to plug in -2 for y into one of the equations.

x-10y=16

x-10(-2)=16

Remember a negative times a negative equals a positive.

x+20=16

Subtract 20 from both sides.

x=-4

Hope this helps!

If not, I am sorry.
