Answer:
a = 8
Step-by-step explanation:
x-1 = 0
x = 1
let x³ + ax² -x -8 be p(x)
hence, p(1) = (1)³ + a(1)² -1 -8 = 0 (since, x-1 is a factor)
= 1 + a - 1-8
= a - 8 = 0
therefore, a = 8
In x^3=64, X is equal to 4
The measure of angle 6 can be found by subtracting the measure of angle 13 from 90.
90-13 = 77
Answer:
D they both are correct, because it is the reflection that are equal to each coordinate.
