Step-by-step explanation:
Assume length of side 2 = L
Area of parallelogram is Height x L
So, 72 = 8 x L
L = 9
S= 15
3s=45
3s/3=45/3
S=15
You have to divide both sides
Answer:
7x - 3 = 60
7x = 63
x = 9
if you need to find for y
11y + 5 = 60
11y = 55
y = 5

Answer:
A. 29i
Step-by-step explanation:
Step 1: Plug in given variables
(2 - 5i)(2 + 5i)i
Step 2: Difference of squares (expand)
(4 - 25i²)i
Step 3: Imaginary numbers rules
(4 - 25(-1))i
Step 4: Combine like terms
(4 + 25)i
(29)i
Your final answer will be 29i
