Answer:
k = -20.
Step-by-step explanation:
Do the division:
4x ) 12x^2 + kx ( 3x
12x^2 + k/4
So k/4 = - 5
k = -20.
Answer:
65°
Step-by-step explanation:
vertical angles are equal.....so if A and B are vertical angles, and A is 65° ,then B is also 65°
FOIL method : F = First , O = Outer , I = Inner, L = Last
(6x-6)(x+6)
First: 6x * x = 6x^2
Outer: 6x * 6 = 36x
Inner: -6 * x = -6x
Last: -6 *6 = -36
Put these in order and we get : 6x^2 + 36x -6x -36
Is it 116? if i didnt add that up wrong thats the answer
