Answer:

(2x - 5y)²

(2x - 5y)(2x - 5y)

2x(2x - 5y) - 5y(2x - 5y)

2x(2x) - 2x(5y) - 5y(2x) + 5y(5y)

4x² - 10xy - 10xy + 25y²

4x² - 20y + 25y²

The answer is B.

HELP PLEASE Rajiv has a liability on his car. How is this BEST demonstrated?
Dennis_Churaev [7]

He has insurance in case of an accident.

Insurance, in legal and financial terms, is a form of risk management, used primarily to protect against the risk of potential financial losses.

Ideally, it is defined as the fair transfer of risk of potential loss from one entity to another in exchange for a reasonable fee. In practice, however, the insurance protection business often results in litigation between the parties concerned.

Generally, it is a contract in which one party agrees to pay for the financial losses of another party as a result of a specified event.

Find y' by implicit differentiation √x +√y =1
AleksandrR [38]
Differentiate both sides with respect to x

\frac{d}{dx}(x^{\frac{1}{2}} + y^{\frac{1}{2}}) = \frac{d}{dx}(1)\\\\ \frac{1}{2x^{\frac{1}{2}}} + \frac{1}{2y^{\frac{1}{2}}}\frac{dy}{dx} = 0\\\\\frac{1}{2y^{\frac{1}{2}}}\frac{dy}{dx} = -\frac{1}{2x^{\frac{1}{2}}}\\\\\frac{1}{2\sqrt{y}}\frac{dy}{dx} = -\frac{1}{2\sqrt{x}} \\\\\frac{dy}{dx} = -\frac{1}{2\sqrt{x}} \times 2\sqrt{y}\\\\\frac{dy}{dx} = -\frac{\sqrt{y}}{\sqrt{x}} \\\\\boxed{\bf{y'= -\frac{\sqrt{y}}{\sqrt{x}}}}

Enrique can spend at most $2240 to renovate his home. One roll of wallpaper costs $32, and one can of paint costs $28. He needs
umka2103 [35]

The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.

<h3>Inequality</h3>

Inequality is the non equal comparison of two or more numbers and variables.

Let x represent the number of wallpapers and y represent the number of cans.

He needs at least 30 rolls of wallpaper and at least 20 cans of paint. Hence:

x ≥ 30   (1);

y ≥ 20    (2)

Also:

32x + 28y ≤ 2240    (3)

Plotting the 3 equations using geogebra online graphing tool, the possible solution is:

(30, 20), (30, 46)

The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.
