B is the second term which is -6
So let’s plug it into the formula
(-6/2)^2
(-3)^2= 9

Answer = 10=21


When you’re multiplying numbers with exponents with the same base (10 is the base) all you have to do is add the exponents

18 and 3 are the exponents we’re dealing with, so we add them and get 21. The base stays the same

10^18 x 10^3 = 10^21

Answer = 10=21

Coordinate form is (x,y) using the variables respectively.

2x+2y=-2
-2y
2x= -2-2y
/2

x=-1-y

9x-6y=36
9 (-1-y)-6y=36
-9-9y-6y=36
+9.
-9y-6y=45
-15y=45
/-15
y=-3

x=-1-y
x=-1- (-3)
x=2
