She spent $23.25, how I got my answer.
I divided $13.50÷2=$6.75 then I added $6.75+3=$9.75 then I added $9.75+$13.50=$23.25.
I hope this helps.
Answer:
-2
Step-by-step explanation:
Hey there!!
if we evaluate the expression it will look like :
3x + 14 = 8
and if we solve it:
3x+14=8
Step 1: Subtract 14 from both sides.
3x+14−14=8−14
3x=−6
Step 2: Divide both sides by 3.
3x/3 = -6/3
x= −2
The average travel time is simply the mean travel time between the given points
- The average time that it takes for the car to travel the first 0.25m is 2.23s.
- The average time to travel just between 0.25m and 0.50m is 0.9s.
- Given the time taken to travel the second 0.25 m section, the velocity would be 0.28m/s.
<u>(a) The average time to travel the first 0.25m</u>
The time travel in the first 0.25m are: 2.24s, 2.21s and 2.23s.
So, the average time to travel is:



<u>(b) The average time to travel just between 0.25m and 0.50m</u>
The time travel in the 0.50m are: 3.16s, 3.08s and 3.15s.
So, the average time to travel this distance is:



The average time to travel between both distance is the difference between the average time of each distance.
So, we have:


<u>(c) The velocity in the second 0.25m section</u>
The distance and time are:


So, the velocity is:

This gives

Answer:
x-√6
Step-by-step explanation:
Non-integer powers of the variable disqualifies the expression from being a polynomial. √x -6 has x to the 1/2 power, so that expression is not a polynomial. Polynomials may have any real or complex, rational or irrational coefficients. (We usually study only polynomials with real coefficients.)
x-√6 is a polynomial
