A+5 = 1 side, so the perimeter is 3(a+5) or P = 3a+15

One side = a + 5
there are 3 equal sides on an equilateral triangle

3(a+5) = 3a+15

How many times will we move the decimal in the dividend? 0.9) 6,815.3

son4ous [18]

Step-by-step explanation:

So when you divide by powers of ten (ten times itself some number of times, like ten, one hundred, one thousand, etc.), the decimal moves to the left. For each power of ten, you move one place to the left. So if you divided a number by one hundred (10^2 or 10*10), you would move two places to the left.
