A^2-2ab+b^2=(a-b)^2
(a-b)^2- c^2= (a-b-c)(a-b+c)

Hope this can help.
Answer: t-13 C
Step-by-step explanation:
If the regular price of a tent is 13 and Harold has a coupon for 13 off, this means Harold has been subsidized by a factor of 13. The amount Harold will pay will be 13 less than t which is t-13 i.e 13 subtracted from the total regular price.
Answer:
y= -3x+1
Step-by-step explanation:
Let's start with the y-intercept (initial value). The y-intercept is where the line intersects the y-axis, so the x value should be 0. Here, the y-intercept is (0,1).
The slope is equivalent to the rise over run. We rise three and go to the left 1 which gives us a slope of negative 3 since we went to the left instead of the right.
Equation for a line:
y=mx+b where m is the slope and b is the y-intercept.
We plug in the slope and y-intercept in and get...
y= -3x+1
Divide 12 by 15
The quotient is 0.8
0.8 is equal to 80%
Your answer is 80%
