Determine the perimeter of the triangle.
3x
x + 6
5x – 7

9x-1

Step-by-step explanation:

The perimeter of the triangle is adding up all 3 sides.

(3x)+(x+6)+(5x-7)=P

9x-1 = perimeter

All I have done is combine like terms.

If there is a... x = something, replace x with the number.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
