They are all like-terms so you can add 7y+3y which equals 10y. Then subtract 10y-17y and you get a negative number; -7y
Answer:
270 in²
Step-by-step explanation:
The area of a parallelogram is given by the formula A = bh.
The base of the parallelogram is 9+9 = 18 inches.
The height of the parallelogram is 15 inches.
This makes the area 15(18) = 270 in²
300-3x=33
Subtract 300 on both sides.
-3x=-273
Divide both sides by -3.
x=91
I hope this helps!
