Answer:
See Explanation
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




Answer:
The regular polygon is a nonagon
Step-by-step explanation:
<u><em>The correct question is</em></u>
What is the name of the regular polygon that each interior angle measures 140゚?
we know that
The formula to find the sum of the interior angles in a regular polygon is equal to

where
n is the number of sides of the regular polygon
a is the measure of each interior angle of the regular polygon
we have

substitute in the formula and solve for n





so
The regular polygon has 9 sides
therefore
The regular polygon is a nonagon
Answer:
16
Step-by-step explanation:
each pound has 3.6 cups
1/4 of a pound can be multiplied
3.6 x 1/4 = 0.9
then we subtract 4 - 3.6 = 0.4 say if the question was for one pound
But we have to find 14.4 cups instead as;
3.6 x 4 = 14.4 = 4 pounds
We go back to 0.9 are first smaller serving = 1/4 cup
14.4/0.9 = 16
