Answer:

Step-by-step explanation:
Given


Required
Determine the actual sales
Represent the actual sales with u


<em>Hence, the total sales can be expressed using y = 200 + x</em>
8x5=40
So the car is 40 inches long
1. is 5 seconds
2. would be about 105 because is goes a tiny bit over 100
So the first thing we need to do is multiply 3*-5, since order of operations dictates it (PEMDAS)

Now, whenever we see a minus negative number, we can think of it as adding a positive number

Now we just add them together

23 is the answer
When we raise something to a power, it really justs means we are multiplying it by itself. 3^2 (3 to the power of 2) means that we are mutliplying 3 by itself: 3•3 = 9 or 3^2 = 9 (there are two 3's)
However, when we rasie something to the 0 power, it equals 1. That is because we are multiplying it by itself 0 times. We are not multiplying it by zero, we are effectively doing nothing at all. 3^0 = 1
