Like terms have same variable with same power. Combine like terms.
From pt 1 to pt 2 there is a three unit change, from pt 2 to pt 3 there is a 3 unit change, from 3 to 4 there is a 5 unit change, and from 4 to 1 there is a 3 unit change. Add those together 3+3+3+5= 14 units is perimeter
To find area: look at image. answer is 30 units

Answer:
$18.90
Step-by-step explanation:
The way to do percentages is actually pretty easy.
since it's taking 30% of you are left with 70%. Take 70 and divide it by 100. This gives you .70
Now what you do is you take the price of the time and multiply it by the .70
So 27.00 * .7 = 18.90
So Noah paid 18.90
Basically, this equation is called the "slope intercept form" and to change into into that, you must simplify the equation.
