Answer:
The perimeter is 52
Step-by-step explanation:
The area is 36x^2 -60x+25
We set this equal to 0 to find the length and width
A= 36x^2 -60x+25
We notice that this is a perfect square trinomial
(a^2 -2ab-b^2) = (a-b)^2
let a = 6x and b=5
A=(6x-5) (6x-5)
The length and width are the same since is it a square (we know it is a square so they have to be equal)
The perimeter of a square is
P =4s
P =4 (6x-5)
Distribute the 4
= 24x -20
Let x =3
P = 24(3) -20
=72 -20
= 52
The perimeter is 52
Answer:
Step-by-step explanation:
The general equation for this is d = s*t. d = distance flown, s = speed that the airplane travels, and t = time. So for this particular probelm you would use
d = 20*s
It would take 4 cups of milk, how I got my answer.
I first needed to know out how much milk was in 1 serving so I divided, 2.5÷5=0.5, so then I multiplied, 0.5×3=1.5, the reason I done this was because there are 3 more servings than the last, then I added, 2.5+1.5=4.
I hope this helps!
