Answer: 17 feet

Step-by-step explanation:

Given : Ms.lu is adding a new room to her house. The room will be a cube with volume 4,913 cubic feet.

Let s be the side of the square-room.

We know that the volume of a square is given by :-

$\text{Volume}=s^3$

Then for the given room we have

$s^3=4,913$

Taking cube root on both sides , we get

$s=\sqrt[3]{4913} =17$

Hence, the length of the new room = 17 feet.

To find this I would use the pythagorean theorem which is:

a^2 + b^2 = c^2

Since we already know c = hypotenuse, and a side of the shorter sides we can plug them it like this:

11^2 + b^2 = 12^2

121 + b^2 = 144

b^2 = 23

√23 = 4.79

Round:

B. 4.8 would be your answer!

For what values of x is the following expression a real number?<br> <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-4" id="

IrinaVladis [17]

The square root is defined only for non-negative numbers. In other words, you can compute $\sqrt{x}$ if and only if $x \geq 0$

If $x \geq 0$ , the square root is a real number, and so is $\sqrt{x}-4$

Is this a irrational or rational number?

Natali [406]

I think its irrational bc if you put it as the squareroot of 329, it results in neverending decimals.

18^2=324+5=329

Answer: x=20
all angles in the triangle are 180 degree, so:
2x+3x+4x=180
9x=180
divide both sides by 9
x= 20
