Which shows how to insert parentheses to make the statement true?

12 – 3 × 2 + 6 = 24
A. (12 – 3) × 2 + 6 = 24
B. 12 – (3 × 2) + 6 = 24
C. 12 – 3 × (2 + 6) = 24
D. 12 – (3 × 2 + 6) = 24

A

Step-by-step explanation:

You always do the parentheses first. Then multiplication/division from left to right. Next adding or subtracting from left to right.

B=12

C= -12

D=0

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
