X = 360 - (122+58+58)
x = 360 - 238
x = 122
39196.75 is the answer to your problem
X/x+9 (original fraction)
x+1/ x+10 = 4/13
x+1=4 so x=3 and x+10=13 so again x=3
now that you have the value of x, substitute it into the original fraction to get:
3/12
The perimeter of R is the same as the perimeter of L
The answer is B.
In the question it says "the intercept of 6" which means the equation has to have +6 in the answer, and there is only one answer choice containing that.
