Answer:
4x
Step-by-step explanation:
C
expand factors, sum like terms and divide by 2
(x + 2)² + (x - 2)² = x² + 4x + 4 + x² - 4x + 4 = 2x² + 8

Answer:The volume of the reservoirs in in^3 is:
V = 30*14*(3/2)*12* (since 1 ft = 12 in)
1 gal = 231 in^3
((7/8)V) : 231 = ((7/8)30*14*(3/2)*12)/231 = 28.64 gal
28.64 gallons of oil are required to fill the reservoir to 7/8 of its depth.
