Answer:
(4d - 3e)(10d - 3e)
Step-by-step explanation:
(4d - 3e)² + 6d(4d - 3e) ← factor out (4d - 3e) from each term
= (4d - 3e)(4d - 3e + 6d) ← collect like terms inside parenthesis
= (4d - 3e)(10d - 3e)
Answer:
0.

Answer:
(3/2,0)
Step-by-step explanation:
Substitute 0 for y and solve for x
Brand A: 32 Diapers, $8.99: about 28 cents per diaper
Brand B: 50 Diapers, $12.49: about 24 cents per diaper
You divide the amount of diapers by the money.
For example, 32 diapers/$8.99 equals about 28 cents per diaper and 50 diapers/$12.49 equals about 24 cents per diaper.
Brand B is the better deal since you save about 4 cents more.
Answer: y=4x^2-40x+107
Just distribute the equation.
y=4(x-5)^2+7
y=4(x^2-10x+25)+7
y=4x^2-40x+100+7
y=4x^2-40x+107
