Answer:
A, B, and C
Step-by-step explanation:
Let's simply the equation first
- -2(-8 - 4y + 3/4)
- 16 + 8y - 1 1/2
What did Daniel do wrong?
Well, let's break down what I did and compare it to Daniel.
- <em>I multiplied -2 and -8x to get 16x. A negative number times a negative number is positive, and 2 times 8 is 16</em>
Daniel, on the other hand, added the two terms.
The first term should be positive (A)
- <em>I multiplied -2 and -4y to get 8y. The same sign rules apply.</em>
Daniel got a negative number, but it is supposed to be positive (B)
- <em>I multiplied -2 and 3/4 should be -6/4, which simplifies to -1 2/4 which is further reduced to -1 1/2</em>
Daniel multiplied and simplified incorrectly (C)
