Answer:
k = 6
Step-by-step explanation:
Solution:
p(x) = 2x^3 + 5x^2 - x - k
x + 2 = 0
x = -2
p(-2) = 2(-2)^3 + 5(-2)^2 - (-2) - k
0 = -16 + 20 + 2 - k
0 = 6 - k
Therefore, k = 6
OPTION (a) 6
PLZ MARK ME AS BRAINLIEST!!!
C. 2x + 3
You have many ways to solve this!
You could...
A) multiply all the answer choices by 3x-2 and see what matches

C) Divide the trinomial by the binomial using long division
Answer:
is this is ur online test ????
7/8 / 2/5 is equal to 7/8 x 5/2 which equals 35/16, 16 goes into 35 twice so there are 2 wholes there is a remaining of 3 so we put it as a fraction over 16
the answer is 2 3/16
Divide by the coefficient of y.
y = (45/9)x
y = 5x
The constant of proportionality is 5.
