Answer:
36
Step-by-step explanation:
AOB + BOC = AOC
AOC = 90 since the lines are perpendicular
6x-12 + 3x+30 = 90
Combine like terms
9x + 18 = 90
Subtract 18 from each side
9x+18-18 = 90-18
9x = 72
divide by 9
9x/9 = 72/9
x = 8
AOB = 6x - 12
= 6*8 - 12
= 48 -12
= 36

It’s 64x2 because when u do the exponent of the x u will get that answer
$30 if it’s not I am so sorry
Ok so the best way to solve this problem is to simplify it as small as possible so first with the given equation 6(x+7)+3x you need to use the distributive property on 6(x+7)
This should get you 6x + 42
Then you have to add everything with like terms (or everything with the variable x) So add together 6x + 3x and that should get you 9x
So now you are left with
9x + 42 which is C
Hope this helps :D
