2. So for this question, you do the distributive property, which is multiplying the term outside of the parenthesis by the terms in the parenthesis. In this case, the outside term is 1/2. 8x * 1/2 = 4x and 1/2 * -16 is -8. That brings us to 4x - 8, which is our answer. Therefore, the correct answer choice is B.
3. Okay. In this problem, we are talking about the sum of 12 and a number. That's 12 + n, because sum means the answer to the addition problem D is out, because we don't do distributive property in this case. The sum of 12 + n is 4n. The expression is 12 + n = 4n. The answer is B.
Answer:
416 in²
Step-by-step explanation:
Given that:
Height. h = 4 in
Length = 12 in
Width = 10 in
The surface area of a rectangular prism is obtained using the relation :
Surface Area, S = 2(lw + lh + wh)
S = 2[(10*12) + (10*4) + (12*4))
S = 2(120 + 40 + 48)
S = 2(208)
S = 416 in²
1/2 and 1/3 are similar because 3/6 and 2/6 are similar. They are so close but not the same.
