Apolygon has sides 3x-1, 2x+2, 7x-3 and 3x. what's the perimeter

The perimeter of a polygon is the sum of lengths of sides.

P = (3x - 1) + (2x + 2) + (7x - 3) + 3x

combine like terms

P = (3x + 2x + 7x + 3x) + (-1 + 2 - 3) = 15x - 2

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
