-x-5
- -5x^2 - 3
or
(-x-5) - (-5x^2 - 3)
First, distribute the -. So then it becomes
-x - 5 + 5x^2 + 3
Since you can't add 5x^2 to -x. You can only combine -5 and 3.
Thus it becomes
- x + 5x^2 -2
However, you order in exponents so
5x^2 - x - 2
would be the correct answer.
Answer:
26 units
Step-by-step explanation:
Pythagoras' Theorem: 
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given
Substitute the given values into the formula and solve for c:




Since length is <u>positive</u>, c = 26 only
