We need to see the graph in order to help
Answer:
Step-by-step explanation:
mP=5x-14
mQ=x-5
mR=2x-9
we know that all the angles in a triangle= 180
that means (5x-14)+(x-5)+(2x-9)=180
5x-14+x-5+2x-9=180 we add the variables and the numbers
8x=180+28
8x=108
x=26
mP=130-14=116
mQ=26-5=21
mR=43
7 + 5 = 12 so is an even number that the ticket the choose
1. Distribute the Negative Signs
2. Combine like terms
-2x^2 + 12x-7
