I got 64 square feet.
My work is shown in the image.
For possible questions:
1: you can find x+7 and x-2 because the sides of the square can be measured as x, and x+7 means 7 more than the original; x-2 means 2 less than the original.
2: solved via factoring. Not sure if you've learned it or not.
3: reject the negative numbers because you can't have negative sides in a square.
Answer:
=9y^2−4
Step-by-step explanation:
3y−2)(3y+2)
=(3y+−2)(3y+2)
=(3y)(3y)+(3y)(2)+(−2)(3y)+(−2)(2)
=9y^2+6y−6y−4
=9y^2−4
Answer:
2/3
