Answer:
25
Step-by-step explanation:
5:9
x:40
what is the realationship between 9 and 40? -9x5=40
so 5x5=25 so x=25
5:9x5:5=25:40
The answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.
The Distributive Property. You are distributing a to x + y.
