The perimeter is all of those sides added together

x+1+x+3+2x+x-2+x

combine like terms

x+x+2x+x+x

6x

1+3+-2

2

6x+2  is the perimeter

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
