B. addition and subtraction
Answer:
x = 16
Step-by-step explanation:
From the first statement, we can say that:
Angle A is equal to angle D,
Angle B is equal to and E.
Since measure of Angle B and E are given and they are equal, we equate them and solve for x.
Hence x = 16
(3x−2)(2x^2+5)
=(3x+−2)(2x^2+5)
=(3x)(2x^2)+(3x)(5)+(−2)(2x^2)+(−2)(5)
=6x^3+15x−4x^2−10
=6x^3−4x^2+15x−10
