Answer:
well let's see below.
Step-by-step explanation:
If you're simplifying the fractional form, the answer would be f(x) + x/2 =4.
The answer is 972 m^2
This is because there are 4 triangles (18*18/2) + one square (18*18) = 972
The sequence can be represented by 
, where 
is a whole number(
and is an integer). By this, we should be able to plug in some whole number x and be able to get these values if they are in the sequence. To test this, let's set these numbers equal to and confirm that there is a whole number x which equals the values selected.
When trying 160 with our equation, we find that x doesn't equal a whole number, thus our answer is C, or 160. To confirm our answer, we can test 170 and 210 and confirm that they both give us a value for x which is a whole number.
