Answer:
y² + 8y + 16
Step-by-step explanation:
Given
(y + 4)²
= (y + 4)(y + 4)
Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is
y(y + 4) + 4(y + 4) ← distribute both parenthesis
= y² + 4y + 4y + 16 ← collect like terms
= y² + 8y + 16
Answer:
30.53
Step-by-step explanation:
24 x 1.06 = 24.44 (6% tax added to 24)
24.44 x 1.20 = 30.53 (20% tip added on top)
To figure out the difference you would subtract 294 from 453.
So 453-294=159
