Step-by-step explanation:
this is essentially
(x-2)(x-3)(x-5) = 0
now to find the cubic function we just expand.
the answer:
x^3 - 10x^2 +31x - 30
Hello
let Brenda drive B miles and Jan drive J miles.
<span>by first sentence : </span><span>B=3J</span>
<span>by 2nd sentence : </span><span>B=J+24</span>
<span>so </span>
<span>3J=J+24</span>
<span>2J=24</span>
<span>J=12</span><span> miles
</span>
Have a nice day
Answer:
2
Step-by-step explanation:
Answer:
Length = 24 and Width = 81
Step-by-step explanation:
Let Width be W
then Length = W-57
Perimeter of rectangle = 2(Length + Width)
=2 (W-57+W)= 210
4W- 114= 210
4W= 324
W= 81
Then Length = 81-57 = 24
Answer:
68.8 metres
Step-by-step explanation:
First, you are given the area of a square, which is 295.84 m^2. The formula for an area of a square is Area =
, where s is the length of one side of the square.
So, if you know that the area of the square is 295.84, you can find the length of one side.
Area = ![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
295.84 = ![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
To solve for s, you can square root each side.
= 17.2, so the length of one side of a square is 17.2 metres.
To get the perimeter, all you have to do is multiply the length of one side of the square by 4, since a square has 4 equal sides.
So, 4 x 17.2 = 68.8 metres.
