Can you please paste a picture of the triangle? I am happy to help, but I need to see the triangle. :-)
Answer:
P=88. L=3w
P= 2(w)+2(L)
Then substitute the values into the equation
88=2w+2(3w)
Then solve for w and its length which is 3w
Answer:
X=16
Step-by-step explanation:
Solve 3(x-9)=21 IF X = 16
16-9 = 7
