Which two statements are correct when simplifying this expression?
12 + 6(3x − 2)
1. First, calculate 6(3x − 2)
2. First, calculate 12 + 6.
3. 12 + 6(3x − 2) = 54x − 36
4. 12 + 6(3x − 2) = 18x
5.12 + 6(3x − 2) = 18x − 24

The expression -4(y – 7) can be simplified by distributing the -4 to both terms inside the parentheses. This gives us -4y + 28.

Therefore, the equivalent expression is -4y + 28.

Option 4, 4y + 28, is incorrect because the sign of -4 is negative and not positive.

The correct statements when simplifying the expression 12 + 6(3x − 2) are:

1. First, calculate 6(3x − 2)
2. 12 + 6(3x − 2) = 18x − 12

Option 3, 12 + 6(3x − 2) = 54x − 36, is incorrect because the distributive property should be applied to both terms inside the parentheses, resulting in 18x − 12 and not 54x − 36.

Option 4, 12 + 6(3x − 2) = 18x, is incorrect because the term -12 from the distributive property is omitted.

Option 5, 12 + 6(3x − 2) = 18x − 24, is incorrect because the expression should be simplified to 18x − 12 and not 18x − 24.

The expression 2(2x + 7) can be simplified by distributing the 2 to both terms inside the parentheses. This gives us 4x + 14.

Therefore, the equivalent expression is 4x + 14.

Option 1, 4x - 14, is incorrect because the sign of 14 is positive and not negative.

Option 2, 4x + 14, is the correct answer.

Option 3, 14x + 4, is incorrect because the coefficients are not multiplied together and the signs are different.

Option 4, 8x + 14, is incorrect because the coefficient of x is 4 and not 8.

To expand the linear expression 3(4x + 3), we can distribute the 3 to both terms inside the parentheses.

This gives us 12x + 9.

Therefore, the correct answer is option 3, 12x + 9.

Options 1, 3/4, and 4 are incorrect because they do not represent the expanded expression.
