One side of a triangle is twice another. the third side is 8 inches and the perimeter of 26 inches. how long is each side?

Side one will be x, and side two will be y.

x = 2y

x + y + 8 = 26

Subtract 8

x + y = 18

Remember that x = 2y

The only value that would make this expression true, is 6.

12 + 6 = 18

Now we can plug these values in to x + y + 8 = 26

12 + 6 + 8 = 26

That's it.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
