Answer:

24.6

Step-by-step explanation:

Given that the length of RT is 43 and that RE is 4x+7 and that ET is 2(x-4), we can use PWP to set up an equation to find the value of x.

4x+7+2(3x-4)  = 43

4x+7+6x-8 = 43

10x = 44

x = 4.4

Then, we plug in 4.4 into the equation.

4*4.4+7=24.6

Sorry for the delay, hope this helps!
