Answer:
it would be C
Step-by-step explanation:
there are two things you need to look at
E(n) = 0.75n and D(E) = 2E
keep the first part in each equation but remember D(E)
plug in E which as far as we know is E(n)
so we get D(E(n))
First, determine the width of the court by dividing the area by the length.
width = area / length
width = 162 m²/18 m = 9 m
Then, determine the perimeter of the court by the equation
P = 2L + 2W
where L and W are length and width, respectively.
P = 2(18m) + 2(9m) = 54 m
Given that every 20 m roll of tape costs $2.79, and even if the court is only 54 m, Jeff still needs to buy 3 20-m roll
total cost = ($2.79) x 3 = $8.37
Thus, the answer is letter B.
Answer:
for only five poinys?
Step-by-step explanation:
Step-by-step explanation:
1=109°
2=3=(360-2*109)/2=142/2=71
Well, first you have to simplify the equation,
y + 7 = 12(x - 5)
y + 7 = 12x - 60
-7 -7
y = 12x - 67
Then graph!
