Question

try again. select the two equations that represent this hanger diagram.
16 = 2(z + 3)
16 = 2(z + 6)
16 = 2z + 6
16 = 2z + 3

Explanation:

Step1: Analyze right side total

The right side has 2 sets of $(z + 3)$, so total is $2(z + 3)$.

Step2: Set equal to left side

Left side is 16, so $16 = 2(z + 3)$.

Step3: Expand the equation

Distribute the 2: $2(z + 3) = 2z + 6$, so $16 = 2z + 6$.

Answer:

16 = 2(z + 3)
16 = 2z + 6
