Answer:
(y^2+5y+25)
Step-by-step explanation:
(y^3 - 125) ÷ (y -5)
Factor the first term. This is the difference of cubes
a^3 – b^3 = (a – b)(a^2 + ab + b^2)
Let a=y and b = 5 (5^3 =125)
(y^3-125) = (y-5) (y^2+5y+25)
Substitute this back into the original equation
(y-5) (y^2+5y+25)
----------------------------
(y-5)
The y-5 term cancels
(y^2+5y+25)
There was a 20% decrease. To find the decrease, subtract the old number from the new number. (30-24=6) Then divide the decrease (6) by the original number and multiply the answer by 100. (6/30=0.2 0.2*100=20).
- 5 r - 6 = - 26 for r = 4
- 5 * ( 4 ) - 6 = - 26
- 20 - 6 = - 26
- 26 = -26
B) true
