Step-by-step explanation:
Get n by itself. It doesn't matter how you do it, you'll get the same answer whether you subtract m or add n to the other side. You just need to have a positive n by itself on one side of the equation.

Answer:
B. 
The function f(x) = (x^2 - 16) / (6x - 24) is discontinuos at
6x - 24 = 0
6x = 24
x = 4.
If the sides are in the ratio of 11:16:24, it means that they are all multiples of a same number x, according to these factors.
So, the shorter side is 11x feet long, the middle one is 16x feet long, and the longest side is 24x feet long.
This means that the perimeter is
feet long. But we know that this is 510 feet, so we have
.
So, the three sides are 110, 160 and 240 feet long.
To find the area of a triangle knowing its three sides, you can use Heron's formula, which states that, if
is half the perimeter of the triangle whose sides are
, the area
is given by

In our case,
so the formula becomes

Answer:

Answer:
The input is 1/7
Step-by-step explanation:
If y =f(x)
Given that f(x) = -7x -2, then y = -7x-2
x is the input
y is the output
Given the output y = -3, we are to find the input value x
Recall that y = -7x-2
On substituting the value of y into the equation
-3 = -7x - 2
-7x = -3+2
-7x = -1
x = -1/-7
x = 1/7
Hence the input is 1/7
