-8 is the correct answer.

(-2)^3 = -8.

So if you take the cubed root of -8, raised to the 3rd power: [3√(-8)]^3

and (-2)^(-3), the answer will be -2.

Therefore, the correct answer is x = -8.

The polygons are similar but not necessarily drown to scale. What is the value of x?
qaws [65]

Answer: 38

Step-by-step explanation:

Since the polygons are similar, the corresponding sides are all in the same proportions.

x-2/4.5 = 16/2 = 48/6

<u>Solving for x</u>

\frac{x-2}{4.5}=\frac{48}{6}

\frac{x-2}{4.5}=8

\frac{4.5\left(x-2\right)}{4.5}=8\cdot \:4.5

x-2=36

x-2+2=36+2

x=38

Therefore, the value of x is 38

2(4x+3)=10x-2<br> Anyone know how to work this out? <br> Working out needed
Step2247 [10]

Answer:

x = 4

Step-by-step explanation:

1. expand.

8x + 6 = 10x - 2

2. Subtract 8x from both sides.

6 = 10x - 2 - 8x

3. simplify 10x - 2 - 8x to 2x - 2.

6 = 2x - 2

4. Add 2 to both sides.

6 + 2 = 2x

5. Simplify 6+2 to 8.

8 = 2x

6. Divide both sides by 2.

\frac{8}{2}  = x

7. Simplify 8/2 to 4.

4 = x

8. switch sides.

x = 4

Therefor, rhe answer is x=4
