Define the population, decide on the sample size (aka what percentage of that population)
Step-by-step explanation:
5.75 miles in 1 hour
= (5.75 * 4) miles in (1 * 4) hours
= 23 miles in 4 hours.
Answer:
5xy*(3y+2)
Step-by-step explanation:
(1): "y2" was replaced by "y^2".
Step by step solution :
Step 1 :
Equation at the end of step 1 :
10xy + (3•5xy2)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
15xy2 + 10xy = 5xy • (3y + 2)
Final result :
5xy • (3y + 2)
4 is a perfect square because it takes 2 * 2 to make 4
