Given EP = FP and GQ = FQ, what is the perimeter of ΔEFG?

x is  

Explanation:

Given:

EP = FP

GQ = FQ

Since the sides are equal, the ΔFPQ and ΔFEG are similar.

According to the property of similarity:

On substituting the value:

Perimeter will be sum of all the sides. If y is known then substitute the value and then find the perimeter.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

i agree because i see the other persons thinking is clear
