Answer:
Width = 4.5
Length = 7.5
Step-by-step explanation:
The perimeter is two times the length plus two times the width.
So 2(x+3) + 2x = 24 is the equation to solve.
2x+6+2x = 24
4x = 24-6
4x = 18
x = 9/2= 4.5
So the width = 4.5
Length = 4.5+3 = 7.5

Answer:
x = 2, x = 6
Step-by-step explanation:
The quadratic can be factored as ...
x^2 -8x +12 = 0
(x -2)(x -6) = 0
Solutions are the values of x that make these factors zero:
x -2 = 0 ⇒ x = 2
x -6 = 0 ⇒ x = 6
The answer to number 9 is 6, 1.
The answer to number 11 is 28.
The answer to number 10 is a hexagon.
The answer to number 12 is 27 and 36.
Hope this helps!

Answer:
![f(g(x))= sign(x(1-x^{2})) = sign(x-x^{3})](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%20sign%28x%281-x%5E%7B2%7D%29%29%20%3D%20sign%28x-x%5E%7B3%7D%29)
Step-by-step explanation:
The height of the portion AB is 10 divided by cos 50 degrees if the CAB, is bent at point A after a storm. The tip of the lamppost touched the ground at point C.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
From the right-angle triangle:
Let's suppose the height of the portion AB is x ft
We know cos is the ratio of the adjacent to the hypotenuse.
From the figure:
![\rm cos50 = \dfrac{10}{x}](https://tex.z-dn.net/?f=%5Crm%20cos50%20%3D%20%5Cdfrac%7B10%7D%7Bx%7D)
ft
Thus, the height of the portion AB is 10 divided by cos 50 degrees if the CAB, is bent at point A after a storm. The tip of the lamppost touched the ground at point C.
