Answer:
hjjjjjjjjjjjjjjjjj
Step-by-step explanation:
Ok then what is the question
What it's asking is to put the equation in either f(x) or g(x).
so for
(a) you would replace all x in f(x) equation with g(x) equation.
f(x) = 3x - 2
f(g(x)) = 3(5x + 4) - 2
solve from there
(b) g(x) = 5x + 4
g(f(x)) = 5(3x - 2) + 4
Reorder the terms:
6 + 14x = 15x
Solving
6 + 14x = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
6 + 14x + -15x = 15x + -15x
Combine like terms: 14x + -15x = -1x
6 + -1x = 15x + -15x
Combine like terms: 15x + -15x = 0
6 + -1x = 0
Add '-6' to each side of the equation.
6 + -6 + -1x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + -1x = 0 + -6
-1x = 0 + -6
Combine like terms: 0 + -6 = -6
-1x = -6
Divide each side by '-1'.
x = 6
Simplifying
x = 6
Answer:
11 units
Step-by-step explanation:
Let's do it this way:
Length = l
width = w
initial equation for area is l * w
We know that l = w+5
substitute.
w+5 * w = 36
solve.
6w = 36
w=6
The width is 6 units.
6+5 = 11
length = 11 units
