D = rt what does r stand for
AnnyKZ [126]
In the equation D = rt, the r stands for rate. The equation is saying that distance equals the rate at which you traveled multiplied with the time you traveled. In other words, r is the speed traveled. Example: If the rate at which you travel is 35 miles per hour and you traveled for 2 hours, then you have traveled 35 miles times 2 or 70 miles.

the measure of one side of a square is (s+3) inches long. which pair of expressions both represent the perimeter of this square?
stich3 [128]
Answer:
perimeter = 4s + 12 inches
perimeter = 4(s+3) inches

Explanation:
We are given that the side length of the square is s+3 inches
In a square, all sides are equal. This means that all four sides are s+3 inches
Now, to get the perimeter, we would add all four sides as follows:
perimeter = s+3+s+3+s+3+s+3 = 4s + 12 inches
For a square, since all sides are equal, we can simply get the perimeter by multiplying the side length by 4 as follows:
perimeter = 4(s+3) inches

Hope this helps :)
