Anuta_ua [19.1K]

<span>2(4x - 12) + 3x = 6x + 1

Distribute.

8x - 24 + 3x = 6x + 1

Combine like terms.

11x - 24 = 6x + 1

5x = 25

Simplify (2x + 3)(x – 4) = ?

Lina20 [59]

Use the FOIL method (first, outside, inside, last) to multiply:

2x^2-8x+3x-12

This can be simplified even more into:

2x^2-5x-12.

Hope this helped!

(14+42-6)/10+7^2 order of operation

Rainbow [258]

Answer:

54

Step-by-step explanation:

$\dfrac{(14+42-6)}{10}+7^2$

Parentheses (14 + 42 - 6) = 50:

⇒ 50/10 + 7²

Exponents 7² = 49:

⇒ 50/10 + 49

Multiplication/division 50/10 = 5:

⇒ 5 + 49

Addition/subtraction: 5 + 49 = 54

⇒ 54
