Answer:
The solution set is {-8, 5}.
Step-by-step explanation:
a^2 + 3a – 40 = 0 .
We need 2 numbers whose product is -40 and whose sum is +3.
They would be + 8 and - 5, so we have the factors:
(a + 8)(a - 5) = 0
Now either a + 8 = 0 or a - 5 = 0, so:
a = -8 or 5.
Answer:
Hmmm... There's no question which leads to the reasoning that there is no answer.
Step-by-step explanation:
Answer:
A) The height of the water increases 2 inches per minute.
Step-by-step explanation:
Slope is the rate of change of height
m = (16 - 12)/(4 - 2) = 4/2 = 2
2 inch per min
Positive slope implies increase
The perimeter of a rectangle is P=2l+2w where l is the length and w is the width.
Plug in values of l and w in:
P=2(x+8)+2(x-1)
P=2x+16+2x-2
P=4x+14
So the perimeter of the rectangle is 4x+14 units
Hope this helped!
