+6 +6
7r-8
The answer is 63!!!!!!!!!!
I'm going to assume the 4 and 3 are exponents and the expression is
.
The first step is to separate the coefficients of 3 and -6 from the variables and to multiply those as normal:

As for the variables, you want to recognize that
means
and
means
, so

In total, there are 7 a's being multiplied, so

Putting this all together, we have:

Answer:
Step-by-step explanation:
Is it just 3x+9, if so the slope is just 3
according to slope intercect form
