Hey there! I'm happy to help!

Since this mural is a square, all the sides are the same. This means that you square on of the sides to get the area (multiply it by itself). If we have the area and want to find a side, we just go backwards and use something called the square root!

If we plug this into our calculators...

√138≈11.74734

We see that is closest to B. 12 ft.

You could also figure this out without a calculator. 138 is very close to 144, which is 12². All the other answer options are way too big.

Have a wonderful day! :D

Which expression is equivalent to (2x + 4)2 – (2x2 + 6)?
Anettt [7]

Answer:

The correct option is B). 2x^{2}+16x+10

Step-by-step explanation:

Given function is (2x+4)^{2}-(2x^{2} +6)

On simplifying,

=(2x+4)^{2}-(2x^{2} +6)

=[4x^{2}+16x+16]-(2x^{2} +6)

=4x^{2}+16x+16-2x^{2}-6

=2x^{2}+16x+10

Thus, The correct option is B). 2x^{2}+16x+10

Which of the following expressions represents the area of a trapezoid with bases of 3x and 5x and a height of 6x?
BaLLatris [955]
Trapezoid Area = (Base1 + Base2) (h/2)
so A = (3x + 5x )(6x/2)= 24x^2

54. log(20x) - log4 = 2​
Luba_88 [7]

Answer:

x=e^2/5

Step-by-step explanation:

log(20 x) - log(4) = 2

Add log(4) to both sides:

log(20 x) = 2 + log(4)

Cancel logarithms by taking exp of both sides:

20 x = 4 e^2

Divide both sides by 20:

And we get Answer:

x = e^2/5

What is Z^6y^3/z^6y^4
Maslowich

Answer:

The correct answer is

Z⁶Y³/Z⁶Y⁴ = 1/Y

Step-by-step explanation:

<u>Points to remember</u>

1).  xᵃ * xᵇ = xᵃ⁺ᵇ

2).  xᵃ/xᵇ = xᵃ⁻ᵇ

3).  x° = 1

4). x⁻ᵃ = 1/xᵃ

The given expression is Z⁶Y³/Z⁶Y⁴

<u>To find the simplification of expression</u>

Z⁶Y³/Z⁶Y⁴ =  Z⁶⁻⁶ * Y³⁻⁴

 =  Z° * Y⁻¹ = 1 * 1/Y = 1/Y

Therefore the value of given expression  Z⁶Y³/Z⁶Y⁴ is 1/Y
