8, 36, 81, 11, 7, 1000

Step-by-step explanation:

A

Lets start with number one.

x^2 = 64.

That means that x times x equals 64.

To find x's value, simply find the square root of 64, which is 8.

So x = 8.

For the second one, the square root of x is 6.

That means that 6 x 6 = x

6 x 6 = 36.

So, x = 36.

B

For the third one, the square root of x is 9.

That means that 9 x 9 = x

9 x 9 = 81

So, x = 81.

For the fourth one, x^2 = 121

That means x times x = 121

To find x's value, simply find the square root of 121, which is 11

So, x = 11.

C

For the fifth one, x^3 = 343.

That means that x times x times x = 343

To find x's value, simply find the square root of 343, which is 7.

So, x = 7.

For the sixth and last one, the cube root of x is 10.

That means 10 x 10 x 10 = x.

10 x 10 x 10 = 1,000

So, x = 1,000

I hope this helps! :)

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
