Answer:

Simplifying

4x + 9 = 12x + -3

Reorder the terms:

9 + 4x = 12x + -3

Reorder the terms:

9 + 4x = -3 + 12x

Solving

9 + 4x = -3 + 12x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

9 + 4x + -12x = -3 + 12x + -12x

Combine like terms: 4x + -12x = -8x

9 + -8x = -3 + 12x + -12x

Combine like terms: 12x + -12x = 0

9 + -8x = -3 + 0

9 + -8x = -3

Add '-9' to each side of the equation.

9 + -9 + -8x = -3 + -9

Combine like terms: 9 + -9 = 0

0 + -8x = -3 + -9

-8x = -3 + -9

Combine like terms: -3 + -9 = -12

-8x = -12

Divide each side by '-8'.

x = 1.5

Simplifying

x = 1.5

Find each product.<br><br> 1. 2x(x^2-6x+3)<br><br> 2. 2a^2(5b^2 + 3ab + 6a + 1)

hoa [83]

Given:

The expressions are:

$2x(x^2-6x+3)$

$2a^2(5b^2+3ab+6a+1)$

To find:

The product of each expression.

Solution:

According to the distributive property of multiplication over addition, we get

$a(b+c)=ab+ac$

The first expression is:

$2x(x^2-6x+3)$

Using distributive property of multiplication over addition, we get

$2x(x^2-6x+3)=(2x)(x^2)+(2x)(-6x)+(2x)(3)$

$2x(x^2-6x+3)=2x^3-12x^2+6x$

Therefore, the product of $2x(x^2-6x+3)$ is $2x^3-12x^2+6x$ .

The second expression is:

$2a^2(5b^2+3ab+6a+1)$

Using distributive property of multiplication over addition, we get

$2a^2(5b^2+3ab+6a+1)=(2a^2)(5b^2)+(2a^2)(3ab)+(2a^2)(6a)+(2a^2)(1)$

$2a^2(5b^2+3ab+6a+1)=10a^2b^2+6a^3b+12a^3+2a^2$

Therefore, the product of $2a^2(5b^2+3ab+6a+1)$ is $10a^2b^2+6a^3b+12a^3+2a^2$ .

47. If the sum of 2r and 2r + 3 is less than

ycow [4]

Answer:

(E) 1

Step-by-step explanation:

2r+ (2r+3 ) < 11

Combine like terms

4r+3 < 11

Subtract 3 from each side

4r +3-3 < 11-3

4r < 8

Divide each side by 4

4r/4 < 8/4

r <2

The only possible choice is 1
