Answer:
1. x²-2x+15
This can't be factored, I've tried multiple ways now, but it just can't be factored.
2. y²-19y+90
Let's factor y^2−19y+90
y^2−19y+90
The middle number is -19 and the last number is 90.
Factoring means we want something like
(y+_)(y+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -19
Multiply together to get 90
Can you think of the two numbers?
Try -9 and -10:
-9+-10 = -19
-9*-10 = 90
Fill in the blanks in
(y+_)(y+_)
with -9 and -10 to get...
(y-9)(y-10)
Answer:
(y−9) (y−10)

sorry I dont know this... I'm sorry
Y = -5/4x + 2
y = mx + b. MX = slope, b = y int, they alr gave us slope and y-int, so just plug into equation form

Answer:
D.
Step-by-step explanation:
Simply plug in your variables and solve (<em>r </em>= x + 2 and <em>h</em> = 3x + 8):
V = π(x + 2)²(3x + 8)
V = π(x² + 4x + 4)(3x + 8)
V = π(3x³ + 20x² + 44x + 32)
V = 3x³π + 20x²π + 44xπ + 32π
