Answer:
y = ( x-2)(x+7)
Step-by-step explanation:
y = x^2 + 5x - 14
What 2 numbers multiply to -14 and add to 5
-2 * 7 = -14
-2+7 = 5
y = ( x-2)(x+7)
.4minute :
V=πr²h
V=π(1.8/2)²(3.5ft)=.9639ft³×1min/2.3ft³=.419 min
Answer:
(k+3)(k+4)
The zeros are -3 and -4
Step-by-step explanation:
k2+7k+12
The middle number is 7 and the last number is 12.
This means we need two numbers that:
Add together to get 7
Multiply together to get 12
to fit in this equation (k+_)(k+_)
in this equation, it would be 3 and 4
3+4 = 7
3*4 = 12
Now we fill in the blanks to get
(k+3)(k+4)
To get the zeros, use the equations
k+3=0 and k+4=0
You end up with
k=-3 and k=-4
