Answer:
Width=12 inches
Length=15 inches
Step-by-step explanation:
Let's say the width is x.
Then, the length is x+3.
The area of a rectangle is the length times width, so
x(x+3)=180
x^2+3x=180
x^2+3x-180=0
After using the quadratic formula, x comes out to be 12 or -15.
x cannot be -15 because you can't have negative distance, so we are left with x=12.
The width is 12 inches and the length is 12+3=15 inches.
Check: 12*15=180
Answer:
Step-by-step explanation:
b and c are the speeds of the boat in stool water, and current, respectively.
Going with the current, the boat travels b+c=16 km/h.
Going against the current, the boat travels b-c=6 km/h
add the equations together
b+c = 16
b-c = 6
—————
2b = 22
b = 11
c = 16-b = 5
Rounded to the nearest 1%, the cost exceeded the budget by 12%
Answer:
(0, -1), (1, 0), (2, 1)
Step-by-step explanation:
I find this easier to do after multiplying the equation by -1:
y = x - 1
Pick any value for x, then subtract 1 from it to find the corresponding value of y.
