<h3>Linear expression represents the missing length</h3>
<em><u>Solution:</u></em>
The perimeter of the triangle shown is represented by the expression 10x - 1
The lengths of two sides are given: 3x + 1 and 5x - 2
We have to find the length of third side
We know that,
perimeter of the triangle = sum of length of all three sides
10x - 1 = 3x + 1 + 5x - 2 + third side
10x - 1 = 8x - 1 + third side
third side = 10x - 1 - 8x + 1
third side =2x
2x has variable x and its power is 1
Linear expression is an algebraic expression where the power of variable is equals to 1
Thus linear expression represents the missing length
Step-by-step explanation:
= 10x - 5 + 3x - 2
= (10 + 3)x + (-5 - 2)
= 13x - 7
X = -4
As g(x) is replaced by g(-4)
plug in -4 for x inside the equation.
g(-4) = (-4) - 1g(-4) = -5
Plug in -4 for x in f(x)f(-4) = 4(-4) - 4f(-4) = -16 - 4f(-4) = -20
Now solve for f(x) over g(x)
remember, f(x) = -20, and g(x) = -5
-20/-5 = 4
4 should be your answer
