General Formulas and Concepts:
<u>Calculus</u>
- Limit Properties:

- Definition of a Derivative:

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x + 2
<u>Step 2: Find derivative</u>
- Substitute:

- Distribute:

- Combine like terms:

- Divide:

- Evaluate:

Evaluate: 2(1/4) + 2/5 ÷ (-1/2) - 1/4
⇛9/4 + 2/5 ÷ (-1/2) - 1/4
Take the LCM of the 4 and 5 is 20.
Again, 2 and 4 is 4.
⇛[(54+8)/20] ÷ [(-2 - 1)/4]
⇛62/20 ÷ (-3/4)
⇛62/20 × 4/-3
⇛62/{5*(-3)}
⇛62/-15.
Well then multiply 400 x 142 and get your answer of 56,800
The answer is 24 the first choice
