To do this problem, you need to use the Pythagorean thermion I think.
Here is what I got as an answer
22.5 km
Answer:
100 miles
Step-by-step explanation:
We need to read the graph to determine the answer.
The input is 10 hours
Using the x, go up until you hit the red line and read the y value
The y value is 100 miles
Answer:
approximately 6.708 feet
Step-by-step explanation:
We use the Pythagorean theorem to solve the problem, using 3 feet and 6 feet as the legs of a right angle triangle. The diagonal of the screen is therefore the "hypotenuse" of this right angle triangle, and can be determined via the formula:

which is approximately 6.708 feet
A.
To solve, you need to get the variable by itself.
Order of operations:
Square root both sides.
(x-5)= plus/minus root 3, as 3 is not a perfect square.
Now you need to add 5 to both sides to get it to disappear on the side with the x.
x=root3 +or - 5, which can be rearranged so that 5 is the first term.
