Answer:

42.875

Step-by-step explanation:

First you find the x-intercepts and the vertex of the equation.

(-5, 0), (-2, 0), (-3/2, 49/4)

You use those coordinates to find the sides of the triangle and then you use the lengths to find the semiperimeter.

Lastly, you use Heron's formula to compute the area.

Pleas answer this in two minutes
Ainat [17]

Answer: x=5, y=7

Step-by-step explanation:

Since ΔEFG and ΔHIJ are congruent, we can set the corresponding sides equal to each other.

y+14=3y                               [subtract both sides by y]

14=2y                                   [divide both sides by 2]

y=7

------------------------------------------------------------------------------------

10x=x+45                            [subtract both sides by x]

9x=45                                 [divide both sides by 9]

x=5
