Answer:
The length of a rectangle is 7 inches longer than it is wide. If the area is 170 square inches, what are the dimensions of the rectangle?

x = width x + 7 = length
x(x+7) = 170
x^2 + 7x - 170 = 0
(x + 17)( x - 10)
Therefore x = 10 as x = -17 no answer.
Width = 10 inches
Length = 17 inches
C) A=S^2
Step-by-step explanation:
C= -1/5
B= -0.4
C= -3/7
Answer:(-1,3)
150 = x
We can use a ratio to solve
100 batches x batches
------------------- = ---------------------
8 hours 12 hours
Using cross products
100 * 12 = 8x
1200 = 8x
Divide by 8
1200/8 = 8x/8
