Question 4 (6 points) Audrey simplified an expression. Her work is shown below.
3 (4x + 2y – 6)
Step 1: (3 * 4x) + (3 * 2y) + (3 + 6)
Step 2: 12x + (3 * 2y) + (3 * 6)
Step 3: 12x + 6y + (3* 6)
Step 4: 12x + 6y + 18
.

Correct Audrey's mistake by simplifying the original expression correc
points)

Audrey made a mistake in Step 1. Audrey's mistakes were adding 3 and 6 instead of multiplying 6 with 3, Also, the addition symbol in-between the expressions (3*2y) and (3+6) should be changed to a subtraction symbol.

Step-by-step explanation:

Corrected expression:

3 (4x + 2y - 6 )

Multiply all values inside the parentheses by 3.

3 (4x) + 3 (2y) - 3 (6)

Solve for the answer.

12x + 6y - 18

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
