Answer:
D) 2x^2 + 11x^3 + 12x^2 - 10x - 8
Step-by-step explanation:
you multiply each term of the first expression with each term of the second expression and add all the terms
so start with x^2 * 2x^2 = 2x^4
x^2 * 3x = 3x^3
x^2 * -4 = -4x^2
4x * 2x^2 = 8x^3
at this point it's clear that the correct answer is D but we can continue
4x * 3x = 12x^2
4x * -4 = -16x
4x^2
6x
-8
by adding
2x^2 + 11x^3 + 12x^2 - 10x - 8
A. T+7=-13,
-13-7= -20,
-20+7=-13,
T = -20,
B. N-12=17,
29-12=17,
N = 29
