Let the number be x
5 x = 8 + 3x
2 x = 8
x = 4 Ans
Answer:
perimeter =
8
x
+
4
Explanation:
the perimeter of a rectangle is ∙ perimeter =
2
l
+
2
w
where l is the length and w the width
here
l=
3
x
−
2
and
w
=
x
+
4
⇒
perimeter =
2
(
3
x
−
2
)
+

(
x
+
4
)
←
distribute
⇒
perimeter =
6
x

+
2+8
←
collect like terms
⇒
perimeter =

Answer:
13
Step-by-step explanation:
Volume to find radius: ![(3\frac{V}{4\pi})^1^/^3](https://tex.z-dn.net/?f=%283%5Cfrac%7BV%7D%7B4%5Cpi%7D%29%5E1%5E%2F%5E3)
Substitute: ![(3\frac{9198.1}{4\pi})^1^/^3](https://tex.z-dn.net/?f=%283%5Cfrac%7B9198.1%7D%7B4%5Cpi%7D%29%5E1%5E%2F%5E3)
Solve: ![(3(732.3))^1^/^3](https://tex.z-dn.net/?f=%283%28732.3%29%29%5E1%5E%2F%5E3)
![2196.9^1^/^3](https://tex.z-dn.net/?f=2196.9%5E1%5E%2F%5E3)
13≈r
The answer is b
as the formula is
y-y1=m(x-x1)
y-6=-2/3(x-4)
