The answer to this is a n = a1 + d(n - 1)
Answer:
6
Step-by-step explanation:
3(x+2) = 4x
3x + 6 = 4x <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside
3x - 3x + 6 = 4x - 3x <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.
6 = x
5 = 60
6 = 150
7 = 30
if you have any more questions let me know
<span>(a+7) * (a-4)
a^2 - 4a + 7a - 28
a^2 + 3a - 28</span>
It is easy try to figure it.
If you did not figure it out the answer is
A. I think is 24 not sure.
B. I think it is 18 not sure.
