Answer:
28x+20
Step-by-step explanation:
So the equation for perimeter is
Sx4 or S+S+S+S
So you would do


Answer:
So to do this you need a protactor and measure it with it, then add the total
Step-by-step explanation:
In short, if the denominator is a decimal or a fraction and you have an integer in the numerator, the numerator gets blown up.
so if you divide by 1/2, the numerator blows up to twice as large, if you divide by 1/5, to five times as large, if you divide by 1/3... well, let's see,

why is that? well, you're dividing, and so is saying "how many times 1/3 goes into 2"?
well, 1/3 + 1/3 + 1/3 = 3/3 or 1, so in 1 whole, the fraction goes there 3 times, so in 2 wholes, it'll be 6 times.
One is that they are all <em>real numbers</em>, or <em>rational numbers</em>.
