<span>2(2x - 4) + x = 7
First of all, apply the distributive property for the parenthesis:
a(b - c) = ab - ac
So, = 4x - 8 + x = 7
Now, bring like terms together:
4x + x = 7 + 8
5x = 15
x = 15/5
x = 3
In short, Your Final Answer would be: 3

Answer: Tthe tower is 129 feet tall.
Step-by-step explanation:
According to trigonometry in a right triangle:
Let x be the height of the tower.
Given ,
Since tower stands vertical to the ground, that means it is making a right triangle with the shadow.
Hence, the tower is 129 feet tall.
For area A, the width will be √(3A/4), so for the three rugs, the widths are 6 ft, 9 ft, 12 ft. Corresponding lengths are 4/3 times that, so are 8 ft, 12 ft, 16 ft.
The rug dimensions are
.. 6 ft x 8 ft
.. 9 ft x 12 ft
.. 12 ft x 16 ft
Pick the one(s) that are on your list.
