In the following pair of polynomials, the second polynomial is a factor of the first. Factor completely x^3+3x^2-18x , x-4
OLga [1]

Answer:

The required factors are: x, (x + 6) and (x - 3).

Step-by-step explanation:

As per the question,

The given polynomial is:

x^{3}+3x^{2}-18x

Now,

BY factorization, we get

x^{3}+3x^{2}-18x

=x(x^{2}+3x-18)

By splitting the mid-term, that is split 3x like:

3x = 6x - 3x

Therefore,

x(x^{2}+6x-3x-18)

Now on further solving by taking common factor out, we get

=x[x(x+6)-3(x+6)]

=x(x+6)(x-3)

Therefore, the given second polynomial (x - 4), is not a factor of given polynomial x^{3}+3x^{2}-18x.

Hence, the given polynomial has three factor x, (x + 6) and (x - 3).

Rose bought a new hat when she was in vacation. If the hat cost $975 and the sales tax was 6%, how much did rose pay for the hat
Rufina [12.5K]

Hi!


To solve this, set up a proportion and cross multiply.


\frac{x}{975} \frac{6}{100}


975 x 6 = 5850

5850/100 = 58.5


58.5 + 975 = 1033.5


The answer is $1033.5


Hope this helps! :)

a triangle has an area of 38.4cm.the height of the triangle is 12.8cm.what is the length of the base of the triangle​
Solnce55 [7]

Answer: 6  cm

Step-by-step explanation:

Use equation for area of triangle

A=a*h/2

a*h=2A

a=2A/h

where a  represents base of triangle

h represents height of triangle.

h=12.8 cm

A=38.4 cm²

a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm= 6 cm
