10, 20, and 18.
The pattern is x2 -2, so that's how you get those.
Its 2.25 just took test 100%
Answer:
100 - 4q²
Step-by-step explanation:
(10 - 2q)(10 + 2q)
each term in the second factor is multiplied by each term in the first factor.
10(10 + 2q) - 2q(10 + 2q) ← distribute parenthesis
= 100 + 20q - 20q - 4q² ← collect like terms
= 100 - 4q²
36.75 - 28.50= $8.25 dollars earned
0.75 x 49 = 36.75
36.75/49=0.75
36.75/0.75
49 x 0.75 = 36.75
