Answer:
Zeros: 5, multiplicity 1; -4 multiplicity 2; degree 3
y=1(x-5)^1(x+4)^2
y=(x+4)^2(x-5)
y=(x^2+8x+16)(x-5)
y=x^3+8x^2+16x-5x^2-40x-85
y=x^3+3x^2-24x-85
Step-by-step explanation:
I think it is the first answer, but don't count on it! I'm not sure.
Answer:
x² + 10x + 25 = 31
Step-by-step explanation:
To complete the square use half the x coefficent (10/2 = 5)
and square it (5² = 25)
Then add it to both sides
x² + 10x + 25 = 6 + 25
x² + 10x + 25 = 31

Answer:
Step-by-step explanation:
Assume the base is right triangle.
<u>The volume:</u>
<u>Substitute values and solve for h:</u>
- 154 = 1/2(7)(4)h
- 154 = 14h
- h = 154/14
- h = 11 inches
