Step-by-step explanation:
6+3=9
7(9)-4x5
63-4x5
63-20
Answer: 43
We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
statements:
1.) E is midpoint of TP
2) TP bisects MR
reasons:
1.)given
2) MT is congruent to PR (I think)
I might be wrong though so dont count on it being right. I hope I helped. ime not that good at math. I m not BAD but yea
First side is = x
Second side is = 3x-3
Third side is = 44x - 66
Perimeter = Sum of sides
P = x + 3x + 44x -66 -3
P = 48x - 69
