Answer:
k=10
Step-by-step explanation:
g(x)=2x^2+ kx+18
when x=-2
g(-2)=2 (-2)^2 -2k +18
Since when x is -2, y =6
6=2 (-2)^2 -2k +18
6=18+8-2k
2k=26-6
2k=20
k=10

One way to make it easier to multiply, pick a number from a multiplication problem. Then, add the amount of times of the other number.
Example:
6 x 8 = ?
8 = Chosen Number
So, add 8, 6 times.
8 + 8 + 8 + 8 + 8 + 8 = ?
? = 48
