<span>7n + 4 - 5n <= 2(n+2)
Let's simplify these expression first
2n + 4 <= 2(n + 2)
2(n +4) = 2n + 4
The LHS and RHS expressions are the same but the inequality says contrary
Hence 2n + 4 is not less than but equal to 2(n + 2).
7+ 6a >= -4(2-a) - 2a
-4(2-a) - 2a = -8 + 4a - 2a = -8 + 2a. It should be obvious that 7 +6a is greater than the RHS expression.
Suppose a= 2 then we have 7 + 6(2) = 19 while -8 + 2(2) = - 8 + 4 = -4 So it follows that 7 + 6a >= -4(2-4) -2a
4x >= 8. The expression is always true so the equal to option is out.</span>

Answer:
16.97 ft
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Side B = 21 ft
Side c = 27 ft
As we know, formula for right triangle is as follows,
So, by putting the value in the formula, we get,
= 729 - 441
= 288
a = 16.97 ft
Hence, the length of the side for the right triangle is 16.97ft.
