Answer: 20x + 20

Step-by-step explanation:

We will distribute the four into the expressions to expand, then we will simplify.

Given:

4(2x + 3) + 4(3x + 2)

Distribute:

8x + 12 + 12x + 8

Combine like terms with addition:

20x + 20

(30 POINTS AND BRAINLIEST) Show all work to solve 3x^2 + 5x − 2 = 0.

Dahasolnce [82]

Answer:

The answer to your question is: (x + 2)(3x - 1) = 0

x1 = -2

x2 = 1/3

Step-by-step explanation:

3x² + 5x − 2 = 0

Multiply 3 x -2 = -6

Find two numbers that added = +5 and multiply -6

These numbers are +6 and -1

Then:

3x² + 6x -1x − 2 = 0

Factorize 3x (x + 2) - 1(x + 2) = 0

Factorize again (x + 2)(3x - 1) = 0

Finally

x + 2 = 0 3x - 1 = 0

x = -2 x = 1/3

The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is: b

Dennis_Churaev [7]

Answer:

The real distance is $600,000\ cm$ or $6\ km$

Step-by-step explanation:

we know that

The scale of the map is $1:1,000,000$

that means

1 cm in the map-------> represent 1,000,000 cm in the actual (real distance)

by proportion

$\frac{1}{1,000,000}=\frac{0.6}{x}\\ \\x=0.6*1,000,000\\ \\x=600,000\ cm$

Remember that

$1\ km=100,000\ cm$

$600,000\ cm=6\ km$
