Answer:

The resultant expression is 6 x^3 - 4 x^2 - 8 x - 16.

Step-by-step explanation:

The given expression is

(3x^2+4x+4)(2x-4)

Using distributive property, the above expression can be written as

3x^2(2x-4)+4x(2x-4)+4(2x-4)

6x^3-12x^2+8x^2-16x+8x-16

6 x^3 - 4 x^2 - 8 x - 16

Therefore the resultant expression is 6 x^3 - 4 x^2 - 8 x - 16.

Solve for X. The Triangles in each pair are similar
Klio2033 [76]

Answer:

x = 7

Step-by-step explanation:

In this question, we need to find what the value of x is.

To do so, we need to find the value of the change of the triangle, since the triangles are basically the same

We know to get from 18 to 27, we would need to multiply 18 by 1.5.

This means that the triangle "BCD" is increasing from 1.5 to get "JKL"

With this knowledge, we also know that side CB, 10, needs to increase by 1.5

When you multiply 10 by 1.5, you get 15.

The triangle side "JK" is the same side as "CB", so we need to find what makes the value of 15 for the "JK" side.

To do this, solve 3x-6 for 15.

3x - 6 = 15

Add 6 to both sides.

3x = 21

Divide both sides by 3

x = 7

The x-variable would be 7.

Using the order of operations rule, solve the following: 12 ÷ 2 + 4 – 2 × 3 = ? A. 36 B. 0 C. 4 D. 24 Mark for review
AlexFokin [52]
<h2>Answer:</h2>

<u>The answer is </u><u>(C) 4</u>

<h2>Step-by-step explanation:</h2>

According to the rule of BODMAS

We will first do division then Multiplication then addition and in the last we do subtraction

So

12 ÷ 2 + 4 – 2 × 3 will be done as

= (12 ÷ 2) + 4( – 2 × 3)

= 6+4-6

= 4

zloy xaker [14]

Answer:

m = 1

Step-by-step explanation:

11m + 13 = m + 23

<u>Get m by itself by subtracting m from both sides. </u>

10m + 13 = 23

<u>Subtract 13 from both sides.</u>

10m = 10

<u>DIvide by 10.</u>

m = 1
