Answer:
width =5.5ft
length =18
Step-by-step explanation:
w=x
L=2x+7
area=w*L
99 = x(2x+7)



2x(x+9)-11(x+9)=0
(2x-11)(x+9)=0
2x-11=0
2x=11
x=11/2
x=5.5
L=2x+7=2*5.5+7=11+7=18
Since she drank 4.5 mm of slushy per second, she continued to drink for 17 seconds so 4.5•17=76.5 Now that you have how much she drank, add that to how much is remaining (148.5) and the original amount that she drank; the answer is 225 milliliter of slushy
The answer would be 480 and because you multiply 30 times 12 you will get 360 and then you add that to the money he already has which is 120 so the total amount is 480
The constant of the proportional relationship graphed in this problem is of 10.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the points on the graph are: (0,0), (2,20), (4,40), ..., hence the constant is:
k = 40/4 = 20/2 = 10.
