110/55 is what u get if u add them all up
Answer:
51.2%
Step-by-step explanation:
60 square feet = 8640 square inchs
So, 60 square feet = 60 × 144 = 8640 square inchs.
For these kinds of expressions use FOIL (first, outside, inside, last).
-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2
Now combine them all:
-18x^2 + 78xy - 24y^2
