Answer:
14
Step-by-step explanation:
perimeter = sum of all sides
so 75- (15+10+27+9)
= 75- 61
= 14
We have to find the equation for three times a number is three more than twice the number.
Let the number is x.
Three times a number = 3x
Three more than twice the number. = 3+2x
These two equations should be equal.
Hence, we have

Therefore, the equation 3x = 3 + 2x can be used to find the unknown x.
A is the correct option.
I agree with the other guy
Answer:
Option B
Step-by-step explanation:

A(0,4) & B(2,2)

B(2,2) & C(-2,-1)

A(0,4) ; C(-2,-1)

Perimeter of triangle = AB + BC + AC
