Question

the perimeter of an equilateral triangle is 5 inches more than the perimeter of a square, and the side of the triangle is 4 inches longer than the side of the square. Find the side of the triangle

Answer 1

What is giving you problems, the initial set up?

Answer 2

yes

Answer 3

start with what you know:
\[Perimeter_{\Delta}=3*SideLength_{\Delta}\]
\[Perimeter_\square=4*SideLength_\square\]

Answer 4

we can say:
the side length of the triangle can be the variable 't'
the side length of the square can be the variable 's'

now our equations become:
\[Perimeter_\Delta = 3t\]
\[Perimeter_\square=4s\]

after this we can start relating these equations based off the given information

Answer 5

ok thank you that helped me a lot

Answer 6

you've altered the equations?
