To find the area of the triangle, you need to do 9*8=72 then divide by 2 to get 36. to find the area of the square you do 5*5=25. subtract 36-25 to get 11. the area of the unshaded region is 11 centimeters squared.
So according to the problem, the tax should be calculated using the bill.
So 5.5% equals to 0.055.
Then multiply 0.055 and 74.98.
Thus resulting in 4.1239 and when rounded, the answer should be 4.12, C
The answer is x=-6
2+(-3x)+(-7)=-x+19
-3x+-5=-x+19
-3x=x+24
-4x=24
x=-6
