We want to find:

[tex](x^2+2x-3)(4x^2-5x+6)[/tex]

Distribute:

[tex]=(x^2+2x-3)(4x^2)+(x^2+2x-3)(-5x)+(x^2+2x-3)(6)[/tex]

Distribute:

[tex]=(4x^4+8x^3-12x^2)+(-5x^3-10x^2+15x)+(6x^2+12x-18)[/tex]

Rearrange:

[tex]=(4x^4)+(8x^3-5x^3)+(-12x^2-10x^2+6x^2)+(15x+12x)+(-18)[/tex]

(9) d = ³/₂

(10) v = -20

Step-by-step explanation:

(7) [tex]n-\frac{8}{9} = \frac{4}{9}[/tex]

[tex]n-\frac{8}{9} = \frac{4}{9} \\\\Collect \ similar \ terms \ together\\\\n = \frac{4}{9} + \frac{8}{9} \\\\n = \frac{4+8}{9} \\\\n = \frac{12}{9} \\\\n = \frac{4}{3}[/tex]

Answer:

x = -3

Step-by-step explanation:

Distribution

3x(-2) -1(-2) = 20

-6x +2 = 20

Subtraction Property of Equality

-6x + (2 - 2) = (20 - 2)

-6x = 18

Division Property of Equality

(-6x/-6) = (18/-6)

x = -3

To check just plug in x

Answer:

C. 9 - x

Step-by-step explanation:

We are given a sentence expression : 9 more than x.

Let's go over all the expressions and what they say as a setnence.

A. x - 9

This would be x more than 9, since the original number of x is way higher than 9. Making this answer incorrect.

B. 9 * x^9? (I am assuming)

This would be 9 times x, not even the correct property.

C. 9 - x

This would be 9 more than x, though you could say it's addition, the value of 9 is more than x, hence making it subtraction.

D. x + 9

This would be 9 plus x, no number has an official value than another.

Answer:

The dimensions of a rectangular prism are 21 in. by 20 in. by 19 in.

To find:

The volume of the rectangular prism.

Solution:

Let the length, breadth and height are 21 in, 20 in and 19 in respectively.

Volume of the rectangular prism is

[tex]V=Length\times Breadth\times Height[/tex]

[tex]V=21\times 20\times 19[/tex]

[tex]V=7980[/tex]

Therefore, the volume of the rectangular prism is 7980 cubic inches.

Answer:

The side on triangle PQR that corresponds to side LN in triangle MNL is side QR.

Step-by-step explanation:

Triangle PQR is a dilated version of triangle LMN, specifically a dilation of 2, since LN = 12, the corresponding side to it on triangle PQR is side QR because it is twice as big as side LN, which is the dilation value for converting triangle LMN to triangle PQR.

The side of triangle PQR corresponds to side LN in triangle MNL will be QR.

Similar triangle are those which have two pairs of interior corresponding angles are equal or two pairs of corresponding sides are in proportion.

We have,

Two triangles as shown in the given figure,

Now,

Using triangle similarity rule,

i.e.

Sides are in equal proportion,

i.e.

[tex]\frac{LM}{PR} =\frac{MN}{PQ} =\frac{LN}{QR}[/tex]

So,

Put values of sides ,

[tex]\frac{14}{28} =\frac{10}{20} =\frac{12}{24}[/tex]

i.e.

[tex]\frac{1}{2} =\frac{1}{2} =\frac{1}{2}[/tex]

So,

All sides in proportion according to the question,

Now,

The side which is in proportion to side LN is QR.

Hence, we can say that the side of triangle PQR corresponds to side LN in triangle MNL will be QR.
