answer: you're missing the problem
2/5 * 10 = 20/50
0.22 as a fraction 11/50
20/50 is the same as 40/100
11/50 is the same as 22/100
multiply
880/10000
which is 22/250
5w^2 = A
You would multiply the width (w) by 5 because it's 5 times more than twice it's width. Then w (Width) would be to the power of 2 because it's 5 times more than twice its width. And this will all equal the Area (a)
Answer:
Step-by-step explanation:
midline: y = -2 (take the average of the min and max)
