Answer:

4x^2+28x^3 : 4x^2 (7x + 1)

Step-by-step explanation:

4x^2+28x^3

Apply exponent rule: \:a^{b+c}=a^ba^c

x^3=xx^2

=28xx^2+4x^2

Rewrite 28 as 4\cdot \:7:

=4\cdot \:7xx^2+4x^2

Factor out common term 4x^2:

=4x^2\left(7x+1\right)

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)

Which choice is equivalent to the product below when x>0 ?
Rzqust [24]

Answer: x/3 ==> C

Step-by-step explanation:

(2x/3)^1/2 * (x/6)^1/2=

(2x/3 * x/6)^1/2=

(2x^2/18)^1/2=

(2x^2)^1/2 / 18^1/2=

(2x^2)^1/2 / (2*9)^1/2=

(2x^2)^1/2 / 3*2^1/2=

2^1/2 * (2x^2)^1/2 / 3*2=

(2(2x^2))^1/2 / 6=

(4x^2)^1/2 / 6=

4^1/2 * (x^2)^1/2 / 6=

2x/6=x/3 ==> C

The graph shows the functions f(x), p(x), and g(x):
Sidana [21]
The function f(x) is:

f(x)=x

This is because the line f(x) passes through the points (-1,-1), (0,0), (1,1) etc.

The function p(x) is:

p(x)=mx+C

Whereby (m) is the slope and (C) is a constant.

m=-4/3, as m=tan(ω)=O/A=-4/3 as slope is negative.

Now when y=-3, x=-3.

So:

-3=-4/3 *(-3) +C

-3= 4 + C

C=-7

This means that:

p(x)=-4/3x -7

Now, where p(x)=g(x), x=-6.

p(-6)=-4/3 * (-6) -7

p(-6)=24/3 -7

p(-6)=8-7

p(-6)=1

Therefore:

p(x) and g(x) meet at (-6, 1) and the solution to p(x)=g(x) is x=-6.

Find the matrices of ​
aniked [119]

\huge{\sf \left[{x-2y\atop 6x-2z}\:\:\:{4y-3\atop 2y-z}\right]=\left[{-3\atop 4}\:\:\:{5\atop 3}\right]}

Creating equations

\\ \sf\longmapsto x-2y=-3\dots(1)

\\ \sf\longmapsto 4y-3=5\dots(2)

\\ \sf\longmapsto 6x-2z=4\dots(3)

\\ \sf\longmapsto 2y-z=3\dots(3)

  • From eq(2)

\\ \sf\longmapsto 4y-3=5

\\ \sf\longmapsto 4y=5+3

\\ \sf\longmapsto 4y=8

\\ \sf\longmapsto y=\dfrac{8}{4}

\\ \bf\longmapsto y=2

  • Put the value in eq(1)

\\ \sf\longmapsto x-2y=-3

\\ \sf\longmapsto x=-3+2y

\\ \sf\longmapsto x=-3+2(2)

\\ \sf\longmapsto x=-3+4

\\ \bf\longmapsto x=1

  • Put the value in eq(4)

\\ \sf\longmapsto 2y-z=3

\\ \sf\longmapsto z=2y-3

\\ \sf\longmapsto z=2(2)-3

\\ \sf\longmapsto z=4-3

\\ \bf\longmapsto z=1
