You have to distribute the 7 to x and 2 so :
7x+14=2x-1
Add one to both sides (inverse operations)
7x+14=2x-1
+1 +1
7x+15=2x
Cross Cancel by subtracting 7x from both sides
7x+15=2x
-7x -7x
15=-5x
Divide by -5
15/-5= -5/-5
X= -3
Answer:
(m-15)(m+2)

(m-15)(m+2)
Answer: f(x) is normally the function of x, so whatever x is, when you plug it into the equation, you'll get an answer. f'(x) may be a corresponding point. Like, P is (0,1) and P' is (0,-1). That's usually what ' means in math, the opposite.
The area of the parallelogram is 80in
A =bh
A= 10(8)
A= 80 in^2
Answer:
x=8
Step-by-step explanation:
15/12 = 1.25
