Hope This Helps! Have A Nice Day!!
You multiply the binomial by the whole trinomial.
So 5x^2 (5x^3 - 6x^2 - 5) and then -2x (5x^3 - 6x^2 - 5)
then solve so it is:
25x^5 - 30x^4 - 25x^2 - 10x^4 + 12x^3 + 10x.
Then you simplify to:
25x^5 - 40x^4 + 12x^3 - 25x^2 + 10x

Assuming y is the price each person pays and each person gets and appetizer and a main dish...
y = ($9 + $6) × 4 people × 1/4
y = ($15) × 4 × 1/4
y = $60 × 1/4
y = $15 each
Answer:
D
Step-by-step explanation:
If you're doing to multiply a value by a number, ALL terms in the equation must be multiplied by the same value otherwise you do not have a correct equation.
200 + 80h = 230 + 70h
80h - 70h = 230 - 200
10h = 30
h = 30/10
h = 3...they will charge the same rate at 3 hrs
