Each wall in Keith's room is 121212 meters long and 7\dfrac{7}{8}7 8 7 ​ 7, start fraction, 7, divided by, 8, end fraction meters wide. He plans to paint one wall blue. Each can of paint covers 151515 square meters. How many cans of paint does Keith need to cover the bedroom wall? Choose 1

there will be 35 boys in each team. : )

pls ask

-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

yess

idk whyy this is happening, i cant even read my notification bc i keep getting errors
