Answer:

-7 and 21

Step-by-step explanation:

y-2y=7 (sub x=7 to the equation)

-y=7

y=-7 (not sure of its correct)

if y=-7,

x-2(-7)=7 (sub y=-7 into equation)

x-14=7

Guys help me pls I need it immediately

Answer:

Hey there!

First, we want to find the side length of the large triangle.

1/2bh=y cm^2

bh=2y cm^2

Since b and h are the same here, we have b^2= 2y, $b=\sqrt{2y}$ .

And we have FC= $\frac{\sqrt{2y} }{2}$ .

Area of shaded triangle: $\frac{1}{2} (\frac{\sqrt{2y} }{2})(\frac{\sqrt{2y} }{2})$ .

This is equal to: $\frac{1}{2}(\frac{2y}{4})$ , or y/4.

Let me know if this helps :)
