Select the factored form of the expression. If
it cannot be factored, select "already in
factored form."
49x² + 64y?
Click on the correct answer.
already in factored form (7x + 8y)(7x + 8y)
(7x + 8y)(7x -8y)
49(x² + y2)

This expression is already in factored form

Step-by-step explanation:

There are no way of factoring this.

Hope this helps :)

(7x+5y)(7x+5y)

since it can not be factored.

-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

12.5 feet
