Answer:
x=32
Step-by-step explanation:
sum of interior angles of a triangle = 180
add up all angles and equate to 180
(4x-13)+(x+18)+15=180
5x=160
x=160/5=32
x+18 = 32+18 = 50
4x-13 = 4x32-13 = 128-13 = 115
add up all to check whether ans = 180; 15+50+115=180
step 1 solve for x step 2 after getting the value of x ,substitute and get the value of angles
6n-1
Re-arrange -(1 - 6n)-(-6n + 1)Distrubute -(-6n -1)6n - 1
0
The question doesn’t say that she lifted weights
14+x=84
x=70
The team lost 70 games.
84+70=x
154=x
The team played a total of 154 games.
and the area would be 
.
