Answer:

( 3x² + 5 ) ( x + 2 )

Step-by-step explanation:

3x³ + 6x² + 5x + 10

→ Factor 3x³ + 6x² by taking out the LCM of the number

3x² ( x + 2 )

→ Factor 5x + 10 by taking out the LCM of the number

5 ( x + 2 )

→ Combine the 2 brackets together

( 3x² + 5 ) ( x + 2 )

→ Expand to check its the right answer, if you get 3x³ + 6x² + 5x + 10 then it is correct

( 3x² + 5 ) ( x + 2 ) = 3x³ + 6x² + 5x + 10

At best buy they have a 42" TV that sells for $1250 and is on sale 15% and sales tax is 6%.What is the final cost?

Marat540 [252]

Ok so
sale is 15% off
and add 6% tax

100-15=85
100+6=106

therefor
1250 with 15% discount plus 6% tax means
1250 times 85% times 106% =
1250 times 0.85 times 1.06=1126.25
final cost=$1126.25

Answer:

1. 30 minutes

2. 15 minutes

3. 30 minutes

4. 60 minutes/ 1 hour

5. 45 minutes

Step-by-step explanation:

1. 60 - 45 = 15

15+15 = 30

2. 30 - 15 = 15

3. 45 - 15 = 30

4. 60 - 30 = 30

30 + 30 = 60

5. 60 - 15 = 45

How many solutions does 4(3x+2)=4(2x+3) +4x have?

Diano4ka-milaya [45]

Final Answer: No Solution. 4(3x + 2) = 4(2x + 3) + 4x has 0 solutions.

Steps/Reasons/Explanations:

Hey there! 8 = 12 would have No Solution because 8 doesn't equal 12. An example of 1 solution is 12 = 12.

Question: How many solutions does 4(3x + 2) = 4(2x + 3) + 4x have?

Step 1: Expand.

$12x + 8 = 8x + 12 + 4x$

Step 2: Simplify $8x + 12 + 4x$ to $12x + 12$ .

$12x + 8 = 12x + 12$

Step 3: Subtract $12x$ on both sides.

$8 = 12$

Step 4: Because $8 = 12$ is false, there is no solution.

No Solution

Write an equation for the line parallel to the given line that contains C(4,8);y=-3x+4

Brrunno [24]

Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20

The answer is y = -3x + 20
