5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

-3

Step-by-step explanation:

We need to use the distributive property a couple times to expand the parentheses.

Remember that when expanding parentheses, we find the sum of the products of the outside term with each of the inside terms.

5(x - 4) = 5 * x + 5 * (-4) = 5x - 20

-(2x + 5) = -1 * 2x + -1 * 5 = -2x - 5

Now we have:

5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

Combine all the terms with x:

-x - 20 = 6x + 1

7x = -21

Divide by 7:

x = -21/7 = -3

The answer is thus -3.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
