10 square units.
.........................
To find the cross product, you can set this up as a proportion. Please see the attached paper for one of the proportions you could use.
You would then multiply the numbers that are diagonal from each other.
You would have 21(8) = 12x or
168=12x.
Answer:

Step-by-step explanation:
<em>The question is incomplete as the input and output values are not given. However, the question can still be solved by assuming both values</em>
Given

In this case;
x represents the input while g(x) represents the output
Now, assume x = 2; Determine the output.
Here we simply substitute 2 for x in the above expression
i.e.
becomes



Similarly, if x = 5



Also, let's assume g(x) = -21; Determine the input
becomes

Solve for x
