X(x + 3) + x(x - 3) = 2
x^2 + 3x +x^2 - 3x = 2
2x^2 = 2
x^2 = 1
x = +1 and x = -1
answer
x = +1 and x = -1
Answer :36in2
example:
my math teacher told me
Answer:
-4/1
Step-by-step explanation:
To find the slope, first plot the two points we are given on the provided coordinate plain. Then using rise/run (slope) find the distance between the two points going up and over or rising and running. So we go up 4 and over 1, this means the slope is 4/1. Since the line we just graphed is going top left towards bottom right, it is negative.

Option B
5(x+3)=7x-3 which is the equation, then we solve for it, and the answer is 9
