Answer:
7y+6
Step-by-step explanation
You have to do 2 times y first. That is 2y. Then you have to add 2y plus 5y, which is 7y. 7y plus 6 equals 7y+6.
Let the width be w, then length = 2w - 1
Area = length times width = w(2w - 1) = 21.
Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0
Solving the quadratic equation gives that w = 3.5.
Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.
Answer: 300*0.73^x
Step-by-step explanation:
300 is the initial value and every time x goes up by 1, the value get multiplied by 0.73
when x=3
then the value would be 300*0.73*0.73*0.73 or 300*0.73^3
then for x amount of times the equation would be 300*(0.73 x times ) or 300*0.73^x
