Answer:
FOIL IT:
First multiply the first terms in each parenthesis.
Outside is next. You multiply the terms on the outer edges of each parenthesis.
Inside is next. Multiply the terms on the inside edge of each parenthesis.
Last: Multiply last terms in each parenthesis.
YOU GET:
3x^2 - 2x - 8
You do 2x20 which is basically 2x2 (4) add a zero and your answer is 40
If a=2 then you would have u=3b-2(2) or u=3b-4 :)
Answer:
1 3/4 gallon or 1.75
Step-by-step explanation:
1 (1/4) = 5/7
5/4 = 5/7
5/4 = 1.25
1.25/x = 5/7
7(1.25) = 5x
5x = 8.75
x = 1 3/4
You have $8.95 per person with 12 people
so you would need to multiply 8.95 and 12
8.95 · 12 = 107.40
the party costs $107.40
