Answer:
Step-by-step explanation:
I tried calculating it hers the resalt
You subtract 7 from 8 and you get 1.
You do not subtract 2 from 2 because they are the same. You have to subtract coordinates that are not the same.
Another way to figure this out would be to plot the points on the coordinate plane and count how many spaces is in between.
The answer is A.1<span />
Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer

when multiplying a positive you move to the right how much multiplied by
when multiplying a negative exponent you move to the left how much multiplied by
