Answer: <u>96</u> sq ft.
Step-by-step explanation:
First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.
A = L * W
A = (10 ft) * (3 ft)
A = 30 ft²
30 ft² * 3 = 90 ft²
Next, we will find the area of the two triangles.
A = 
A = 
3 ft + 3 ft = 6 ft²
Lastly, we will add them together for the total surface area.
90 ft² + 6 ft² = 96 ft²
Explanation:
Consider the case a = -1. Then the expression becomes ...
(-1+1)(-1+1) > (-1-1)(-1-1) . . . . test case
0·0 > (-2)(-2) . . . . . simplified a bit
0 > 4 . . . . . . . . NOT TRUE
_____
If we subtract the right side from both sides, the inequality becomes ...
(a+1)(a+1) -(a-1)(a-1) > 0
a² +2a +1 -(a² -2a +1) > 0
4a > 0
a > 0
The inequality is only true for positive values of "a". For a ≤ 0, the inequality will not be true.
If n is a positive integer that is greater than x and a is a real number or a factor, then a^x/n=n√
a
^x
So I believe a^x/n=n√
a
^x is the answer but I might be wrong.
Hope this helps :)
