Answer:
26.37
Step-by-step explanation:
Apparently, we're to substitute 9 for 4 and recompute:
26.37 = (2.93)9
____
This assumes that the 4 in the expression is the number of boxes, and the (2.93) in the expression is the price per box. The product of those numbers is 11.72, apparently the total cost of 4 boxes of nails.
Answer:
x + 4√(x + 2) + 6
Step-by-step explanation:
All we need to do is expand by using FOIL (First, Outside, Inside, Last):
x + 2 + 2√(x + 2) + 2√(x + 2) + 4
Then we combine like terms to get our final answer:
x + 2 + 4√(x + 2) + 4
x + 4√(x + 2) + 6
