Answer:
x + y = 4 Equation 1
y = 2x -1 Equation 2
-2x + y = -1
x + y = 4
Subtract
You will get
- 3x = -5
Divide by -3
-3x / -3 = - 5 /-3
x = 5/3
Substitute x into equation 1
x + y = 4
x = 5/3
5/3 + y = 4
y = 4 - 5/3
y = 7/3
x = 5/3 y = 7/3
Hope this helps.
I think it’s not a different of squares because when u factor it =2(y-8)
As you can see from the polygon, 70/10= 7.
The second polygon is an enlargement of the first one.
Just multiply 4*7 to get the answer.
4*7= 28
That's the answer!
I hope this helped you!
