Answer:
To solve for y, you want to use the distributive property
First you want to distribute the 8 through the 3y-5 and the 9 through the y-5
8(3y-5)= 24y-40
9(y-5)= 9y-45
24y-40=9y-45 (get the x on one side, so first add 40 to each side)
24y=9y-5 (now subtract 9y to each side)
15y=-5 (divide both sides by 15)
y= -5/15= -1/3
Hope this helps ;)
The first one because if you add all the positives you get 4 and then if you add all the negatives you get 7 so then you do 4+(-7)= -3
6 times 12= 72. 72 times 7= 504. 504 square ft.
3k²+11k+6, or (k+3)(3k+2), which is the 3rd one. :)
