10. A rectangle is 8 feet long and 6 feet wide. If each side is increased by the same amount, the the length and the width of the new rectangle.
area of the new rectangle is 72 square feet more than the area of the original rectangle. Find the length and the width of the new rectangle

2r= 2300

r =1150

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
