Answer:
Step-by-step explanation:
<u>Let's factor the trinomial:</u>
- x² + 14x + 40 =
- x² + 4x + 10x + 40 =
- x(x + 4) + 10(x + 4) =
- (x + 4)(x + 10)
x + 4 is between the answer options
Correct option is D.
Answer:
y = 8.9
Step-by-step explanation:
8^2 + y^2 = 12^2
64 + y^2 = 144
subtract 64 from both sides
y^2 = 80
square root both sides
y = square root 80
y = 8.9
Answer:

Answer:
(3,1)
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other
y = 3x-8
y = 4-x
3x-8 = 4-x
Add x to each side
3x+x-8 = 4-x+x
4x-8 = 4
Add 8 to each side
4x-8+8 = 4+8
4x = 12
Divide each side by 4
4x/4 =12/4
x=3
Now we can find y
y = 4-x
y = 4-3 =1
