Answer:
66.24 (This answer does not match to any of the options...)
Step-by-step explanation:
This shape can be divided into 2 different shapes. A triangle and a rectangle.
Area of a Triangle = × base × height
= × 8.8 × 7.8
= 34.32
Area of a Rectangle = Length × Width
= (19.2 - 7.8) × (8.8 - (3+3))
= 11.4 × 2.8
= 31.92
Total area = 34.32 + 31.92 = 66.24
Answer:
Proved.
Step-by-step explanation:
The functions are:
1.) f(x) = 3x - 27 (* <em>I am giving an answer using this equation. Perhaps you did't copy the question well!</em>)
2.) g(x) = + 9
If two functions are inverses of each other, then:
f(g(x)) = x and g(f(x)) = x situation must be satisfied.
f(g(x)) = 3() + 27
We simply it to get;
f(g(x)) = x - 27 + 27 = x (*<em>This is correct)</em>
<em />
g(f(x)) = (3x - 27) + 9 = x - 9 + 9 = x (* <em>This is also correct!</em>)
