Answer:
The dimensions are (2y+5) by 2(y-1) or 2(2y+5) by (y-1)
Step-by-step explanation:
4y^2 + 6y – 10
Factor the expression
Factor out the greatest common factor
2 ( 2y^2 +3y -5)
2 ( 2y+5) ( y-1)
A = l*w
70?
21.25 inches is the width
27.5/11 = 2.5 means that the projected image is 2.5 times bigger than the transparency so 8.5*2.5 is 21.25
6 and 12 are two common factors
