Answer:

Step-by-step explanation:

1. 6x + 12 = 3x - 27

3x + 12 = -27

3x = -39

x = -13

2. 2p - 3 = 3p + 2

-p - 3 = 2

-p = 5

p = -5

3. 6x - 2 - 35x -28 = 18x - 27

-29x - 30 = 18x - 27

-47x - 30 = -27

-47x = 3

x = -3/47

What is the value of b in the equation 3b + 2(b - 1) =8

WARRIOR [948]

Answer:

b = 2

Step-by-step explanation:

In order to find the value of b, we have to isolate b on one side of equation first

So,

$3b+2(b-1)=8$

Multiplying 2 with b-1

$3b+2b-2=8\\5b-2=8$

Adding 2 on both sides

$5b-2+2=8+2\\5b=10$

Dividing by 5 on both sides

$\frac{5b}{5}=\frac{10}{5} \\b=2$

So the value of b is 2 ..

<h3>Answer:</h3>

A. $6x^2$ +-5x+14x+-35

$6x^2$ +9x-35

B. $5x^4+-3x^3+10x^3+-6x^2$

$5x^4+7x^3-6x^2$

C. $25x^2+-20x+20x+-16$

$25x^2-16$

D. $x^4+-4x^2+-7x^2+28$

$x^4-11x^2+28$

$====================================$

Step-by-step explanation:

A. (3x*2x)+(3x*-5)+(7*2x)+(7*-5)

Multiply and simplify.

$6x^2$ +9x-35

B. ( $x^2*5x^2$ )+( $x^2*$ -3x)+(2x $*5x^2$ )+(2x $*-3x$ )

Multiply and simplify.

$5x^4+7x^3-6x^2$

C. $(5x*5x)+(5x*-4)+(4*5x)+(4*-4)$

Multiply and simplify.

$25x^2-16$

D. $(x^2*x^2)+(x^2*-4)+(-7*x^2)+(-7*-4)$

Multiply and simplify.

$x^4-11x^2+28$

I hope this helps!

But you should really do this yourself.
