0.75×7=5.25
David ran 5.25 miles in 7 days
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
The answer is 16,300. To get the answer, you just move the decimal over 4 places to the right and add your zeros in.
hopefully this helps
