Simplify the sum. (8u^3+8u^2+6)+(4u^3-6u+3)

rewona [7]

Answer:

$\boxed{12u^3+8u^2-6u+9}$

Step-by-step explanation:

$(8u^3+8u^2+6)+(4u^3-6u+3) = 8u^3+8u^2+6+4u^3-6u+3$

Once

$8x+4x = 12x, \text{ as } x = u^3$

$8u^3+8u^2+6+4u^3-6u+3 = 12u^3+8u^2+6-6u+3 = \boxed{12u^3+8u^2-6u+9}$

You don't need to factor.

ILL GIVE BRAINLIEST!!!!!

Answer:

The answer to question 3 is : 2x^2 + 5x + 3

Step-by-step explanation:

The FOIL method is multiplying the first variables, the outside variables, the inside variables and the last variables.

(2x + 3)(x + 1)

F = 2x times x = 2x^2

O = 2x times 1 = 2x

I = 3 times x = 3x

L = 3 times 1 = 3

2x^2 + 5x + 3

I'll leave the rest to you. You got this!

What is the solution of the equation: 2/3(15x-6)=8(x+1)

madreJ [45]

Answer:

x=6

Step-by-step explanation:

To solve, we need to get the variable, x, by itself. To do this, first, move all the variables to one side of the equation, and the numbers to the other

2/3(15x-6)=8(x+1)

First, distribute the 2/3 on the left

2/3*15x + 2/3*-6=8(x+1)

10x-4=8(x+1)

Next, distribute the 8 on the right

10x-4=8*x + 8*1

10x-4=8x+8

Subtract 8x from both sides

10x-8x-4=8x-8x+8

2x-4=8

Add 4 to both sides

2x-4+4=8+4

2x=12

Now all the numbers are on one side, and the variables are on the other. x is not by itself though, it is being multiplied by 2. To undo this, divide both sides by 2

2x/2=12/2

x=6
