Answer:
the answer is h 86.8 first you gotta take all the numbers then drop the two lowest then you multiply the ones you hsve left then divide it by the number of grsdes there is
Step-by-step explanation:
2y+9= 4
2y=-5
y=-5/2
y= -2and 1/2
For 5 taccos 2 cups cheese is needed.
So 10 taccos is 2*(5 taccos)=2*2 cups cheese =4cups



So to convert taccos to cups of cheese multiply by 2/5 and from cups of cheese to taccos multiply by 5/2.
P⁴ - 81
p⁴ + 9p² - 9p² - 81
p²(p²) + p²(9) - 9(p²) - 9(9)
p²(p² + 9) - 9(p² + 9)
(p² - 9)(p² + 9)
(p² + 3p - 3p - 9)(p² + 9)
(p(p) + p(3) - 3(p) - 3(3))(p² + 9)
(p(p + 3) - 3(p + 3))(p² + 9)
(p - 3)(p + 3)(p² + 9)
The answer is (3).
