Expand, answer should be a polynomial in standard form (5a+2)(a+4)=

castortr0y [4]

Answer:

The standard form of the expression (5a+2)(a+4) is $5a^{2} + 22 a + 8$ .

Step-by-step explanation:

Here, the given expression is (5a+2)(a+4).

Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)

= $5a^{2} + 20 a + 2a + 8$

= $5a^{2} + 22 a + 8$

or, $(5a+2)(a+4) = 5a^{2} + 22 a + 8$

Also, Standard Quadratic form is $ax^{2} + bx + c = 0$

Hence, the standard form of (5a+2)(a+4) is $5a^{2} + 22 a + 8$ .

Solve the following proportion. 15/21=5/x A. 3 B. 105 C. 7 D. not given

Slav-nsk [51]

If you would like to solve the following proportion 15 / 21 = 5 / x, you can do this as follows:

15 / 21 = 5 / x /*x
15 / 21 * x = 5 /*21
15 * x = 5 * 21 /15
x = 5 * 21 / 15
x = 7

The correct result would be C. 7.

Differentiating Functions of Other Bases In Exercise, find the derivative of the function.

aniked [119]

Answer:

$\dfrac{dy}{dx} = \frac{2x-3}{\ln 16(x^2 - 3x)}$

Step-by-step explanation:

We are given the following in the question:

$y = \ln {16}(x^2 - 3x)$

We have to find the derivative of the given expression.

$y = \ln 16(x^2 - 3x)\\\text{Using the log propert}\\\\\log_a b = \dfrac{\log b}{\log a}\\\\dfrac{d(x^n)}{dx} = nx^{n-1}\\\\\dfrac{d(\log x)}{dx} = \dfrac{1}{x}\\\\\text{\bold{Differentiating we get}}\\\\\displaystyle\frac{dy}{dx} = \frac{d(\ln 16(x^2-3x))}{dx}\\\\= \frac{1}{16(x^2-3x)})\frac{d(x^2-3x)}{dx}\\\\=\frac{1}{\log 16(x^2-3x)}(2x - 3)\\\\= \frac{2x-3}{\ln 16(x^2 - 3x)}$

$\dfrac{dy}{dx} = \frac{2x-3}{\ln 16(x^2 - 3x)}$
