If f(x) = 3x^2 and g(x) = x+2 find (f•g)(x)

Alex777 [14]

Answer:

(f*g)(x) = 3x^3 + 6x^2

Step-by-step explanation:

Since we are looking for the result of multiplying the equations (f*g), we must multiply the right sides together

(f*g)(x) = (3x^2)(x+2)

To get from here to the solutions, we must multiply the first term by all parts in the second term

3x^2 * x = 3x^3

3x^2 * 2 = 6x^2

from there, just put them back in the equation

(f*g)(x) = 3x^3 + 6x^2

Which expression is equivalent to \frac{10q^5w^7}{2w^3}.\ \frac{4\left(q6\right)^2}{w^{-5}} for all values of q and w where the

mestny [16]

Answer:

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}} =20q^{17}w^9$

Step-by-step explanation:

Given

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

Required

Determine the equivalent expression

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

Simplify the first fraction

$\frac{5q^5w^7}{w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

Apply law of indices on the first fraction;

$5q^5w^{7-3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

$5q^5w^4.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

$\ \frac{5q^5w^4*4\left(q^6\right)^2}{w^{-5}}$

Apply law of indices:

$5q^5w^4*4\left(q^6\right)^2 * w^{5}$

Evaluate the bracket

$5q^5w^4*4 * q^{12} * w^{5}$

Collect Like Terms

$5*4q^5* q^{12}*w^4 * w^{5}$

$20q^5* q^{12}*w^4 * w^{5}$

$20q^{5+12}*w^{4+5}$

$20q^{17}w^9$

Hence:

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}} =20q^{17}w^9$

Explain how algebra tiles represent like terms and zero pairs

love history [14]

Answer:

Suppose the two like terms are 2 x and 3 x.So to Represent them with algebra tiles ,

Here shape of tiles = Either Square or rectangle

For example , 2 x=Draw two tiles of same color mark variable x in front of it.For, different values of x, we get different number of total tiles.

3 x= Draw three tiles of same color and mark variable x in front of it.For, different values of x, we get different number of total tiles.

For , Polynomial, 3 x -3,

Draw three tiles representing same color, Mark x over it, and then put negative sign in front of it, and draw three tiles of any other color.

To represent Zero,

We can write it as, x -x or p-p

Draw two tiles of same color , and mark negative sign in between .

General formula: A x - A x

Draw A tiles of same color, twice.And mark negative sign in between.
