<h2>f(-2) = 23</h2>
Step-by-step explanation:

If you want to leave a 15% tip, use the fact that 15% = 10% + 5%. Calculate 10% of the bill by moving the decimal point one position to the left. Then, take that number, divide it in half, and add the new amount to the original 10%
8*6*4= 192m^2
8m*6m* 4 sides of those measurements
4*6*2= 48m^2
192+48= 240m^2
