Question 677160: Hello, i'm not sure which category this should go in. I have a question of 'give the perimeter of this triangle in the form of no brackets, and brackets (different questions). The algebraic expression is t+2. How would you work this out?

You can put this solution on YOUR website!

the perimeter of this triangle is equal to the sum of all sides: P=a%2Bb%2Bc

since you are given the algebraic expression t%2B2, it is the length of each side; an equilateral triangle has all sides equal
so, a=t%2B2, b=t%2B2 and c=t%2B2 and P=%28t%2B2%29%2B%28t%2B2%29%2B%28t%2B2%29
P=t%2B2%2Bt%2B2%2Bt%2B2
P=3t%2B6
