Which expression is equal to (2x + 5) · 8 using the commutative property?

5 + 2x) · 8

8 · 2x + 5 · 8

2x + (5 · 8)

(2x + 5 · 8)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
