Final Answer: 
Steps/Reasons/Explanation:
It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).
Question: Simplify the expression:
.
<u>Step 1</u>: Simplify.

<u>Step 2</u>: Simplify.

Use the pythagorean theorem A² + B² = C²
A and B are legs and C is the hypotenuse
so- A² + 12² = 24² A² + 144 = 576
-144 -144
A² = 432 then you have to take the square root
of each side
so- A = √432 or aprox. 20.78
Answer:
50
Step-by-step explanation:
total angle of a triangle should be 180 so we add the given angle and subtract it from 180
If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate
.
We have

Expand the numerator using the binomial theorem, then simplify and compute the limit.

In general, the derivative of a power function
is
. (This is the aptly-named "power rule" for differentiation.)
