Answer:

11) $2x=-4$

Divide both sides by 2:

$\frac{2x}{2}=\frac{-4}{2}$

$x=-2$

12) $2^3\cdot \:2^1=2^{3+1}=2^4$

( $2^4=16)$ if you wanted the exact value.

13) $-3+10=x$

Switch sides:

$x=-3+10$

Rearrange:

$x=10-3$

$x=7$

14) $10^2-64$

$10*10-64$

$100-64$

$36$

15) $\sqrt{100}-5^2$

$10-5^2$

$10-5*5$

$10-25$

$-15$

16) $\frac{1}{4}x=-10$

Multiply both sides by 4:

$4\cdot \frac{1}{4}x=4\left(-10\right)$

$x=-40$

17) $\left(2^3\right)^2=2^{3*2}=2^6$

$(2^6=64)$ if you wanted the exact value.

18) $\left(2^3\right)\left(2^2\right)=2^{3+2}=2^5$

$(2^5=32)$ if you wanted the exact value.

Bryan created a scale drawing of his rectangular bedroom. His drawing had dimensions of 6 inches by 8 inches. If the scale that

vlabodo [156]

Answer:

56 feet

Step-by-step explanation:

If 1 inch = 2 feet, we can first find the actual dimensions of his room by multiplying the number of inches by 2.

6(2)

= 12

8(2)

= 16

So, the actual dimensions of his room are 12 feet by 16 feet.

To find the perimeter, use the perimeter formula, P = 2l + 2w.

Plug in the length and width:

P = 2l + 2w

P = 2(12) + 2(16)

P = 24 + 32

P = 56

So, the perimeter of his actual room is 56 feet.
