Answer:

shared short side: 10x +6
shared long side: 8x +6

Step-by-step explanation:

The factors of the given polynomial are (2x+1) and (x+1). We presume these are the side lengths of each rectangular plot. If the short side (x+1) was common, then the perimeter of the combined lot is ...

4(2x+1) +2(x +1) = 10x +6 . . . units of fence for short side common

If the long side (2x+1) was common, then the perimeter of the combined lot is ...

4(x+1) +2(2x+1) = 8x +6 . . . units of fence for long side common

What’s the derivative of x^2 - 3

geniusboy [140]

Answer:

$\displaystyle \frac{dy}{dx} = 2x$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)$

Derivative Property [Addition/Subtraction]: $\displaystyle \frac{d}{dx}[f(x) + g(x)] = \frac{d}{dx}[f(x)] + \frac{d}{dx}[g(x)]$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle y = x^2 - 3$

Step 2: Differentiate

Derivative Property [Addition/Subtraction]: $\displaystyle y' = \frac{d}{dx}[x^2] - \frac{d}{dx}[3]$
Basic Power Rule: $\displaystyle y' = 2x$

Amy wants to rent a bicycle for the day. The company charges $12 to rent the bike, plus $6 per hour. If Amy has a budget of $42,

Arturiano [62]

Using the equation y=6x+12, where x is the number of hours and y is the total cost for the given value of x, you can plug in 42 for y and solve:

42=6x+12
42-12=6x
30/6=x
5=x

Thus, Amy can rent the bike for 5 hours.
