So, use the distance between two points formula:squareroot((x2-x1)^2+(y2-y1)^2)
squareroot((-7--4)^2+(8-7)^2)
squareroot((-3)^2+(1)^2)
squareroot((9+1)
squareroot(10)
squareroot 10 can be simplified to 3.2 units
Answer:
Step-by-step explanation:
First,, we need to convert the first mixed number to an improper fraction.
Multiply the numbers.
Add the numbers together to finish the mixed number and add it back into the expression.
- 5
Now use the same process I showed above to convert the second mixed number to an improper fraction.
Now subtract the two fractions to find your final answer.
This means that your answer is going to be
or 3
simplified.
