Answer:
yes, idk if thats the answer you are looking for though
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.
42 is 21% of 200. This is because 200*0.21 = 42.

Step-by-step explanation:
Standard form is where the degree of each monomial decreases from left to right. Degree can be found by adding the exponents on each variable.
The only one where this is true is the first one.
The degree goes from 7 to 4 to 2
