Answer:
$28
Step-by-step explanation:
Given that :
Regular price = $35
Discount = 20%
Sale price = Regular price - Discount on sale
Discount on sale = 20% * regular price
Discount on sale = 0.2 * $35 = $7
Sale price = $35 - $7 = $28
D. Add like terms.
So 4x^2+2x^2=6x^2
6x is only x term
6+3=9
So D. 6x^2+6x+9
