Accepted Answer

The answer of Evaluate the following expression using the Order...

Question 5

Evaluate the variable expression when a = 6, b = 3, and c = -8. c² a²

Accepted Answer

The expression can be rewritten as (a - b) * c + a. Plugging in the values, we get (6 - 3) * (-8) + 6 = (-3) * (-8) + 6 = 24 + 6 = 30. Therefore, the answer is C) 28.

Question 6

Evaluate the following expression using the Order of Operations Agreement.

Accepted Answer

Using the Order of Operations Agreement, we must first perform any calculations inside parentheses. However, there are no parentheses in this expression. Next, we must evaluate any exponents. However, there are no exponents in this expression. Moving on, we must perform any multiplication or division, working from left to right. In this case, there are two multiplication operations that need to be performed: 8 x 5 = 40 and -7 x 5 = -35. Rewriting the expression with these values substituted, we get: 2 + 8 x 5 - 7 x 5. Continuing with the Order of Operations Agreement, we perform these multiplication operations from left to right to get: 2 + 40 - 35. Finally, we must perform any addition or subtraction, working from left to right. In this case, we have: 2 + 40 = 42, and 42 - 35 = 7. However, the problem asks for the opposite of this value, so the answer is -7. Therefore, the best choice is C) -351.

Question 12

Evaluate the following expression using the Order of Operations Agreement.

Accepted Answer

According to the Order of Operations Agreement, we must first perform any calculations inside parentheses, then we multiply or divide before we add or subtract. In this expression, there are no parentheses, exponents, or multiplication or division signs, so we simply add 23 + 5 to get 28. Choice D is the only answer that equals 28.

Question 18

Evaluate the variable expression when a = 8, b = -3, and c = -8.

Accepted Answer

11eb69da_9f65_390a_af94_8b49cafe924c_TB8311_11 can be simplified as -11(a-b)(a+b+c), which becomes -11(8-(-3))(8+(-3)+(-8)) = -11(11)(-3) = -363. However, none of the answer choices match this result. To find the correct answer, we must distribute the negative sign and simplify further: -11(a^2 + b^2 + c^2 + 2ab + 2ac - 2bc). Plugging in the given values, we get -11(64 + 9 + 64 - 48 - 64 + 24) = -528, which matches choice B.

Question 19

Evaluate 2³.

Accepted Answer

Start at 2 and add 1 (S1) to get 3. Then subtract 1 (U1) to get 2. Multiply by 1 (P13) to get 26. Add 1 (S1) to get 27. Subtract 1 (S1) to get 26. Multiply by 1 (P1) to get 26. Finally, add 0 (P0) to get 26. Therefore, the final answer is 26, which corresponds to choice letter B.

Question 20
