MULTIPLE CHOICE QUESTION

2 mins • 1 pt

Which expression is equivalent to the following: 4(5a + 3b - 6)?

20a + 3b - 6

20a + 12b - 24

9a + 7b - 2

5a + 12b - 24

I don't know.

Answer explanation

To simplify 4(5a + 3b - 6), distribute 4: 4*5a + 4*3b + 4*(-6) = 20a + 12b - 24. Thus, the equivalent expression is 20a + 12b - 24.

Which expression is equivalent to the expression below? 3x + 5y - 2 + 2x - y + 4

5x + 4y + 2

5x + 4y - 2

5x + 4y + 6

5x + 4y

Answer explanation

To simplify the expression 3x + 5y - 2 + 2x - y + 4, combine like terms: (3x + 2x) + (5y - y) + (-2 + 4) = 5x + 4y + 2. Thus, the equivalent expression is 5x + 4y + 2.

Which expression is equivalent to 9.6 + 4t - 2.3 - 7t?

7.3 - 3t

11.9t

7.3 + 3t

7.3 - t

Answer explanation

To simplify 9.6 + 4t - 2.3 - 7t, combine like terms: 9.6 - 2.3 = 7.3 and 4t - 7t = -3t. Thus, the expression simplifies to 7.3 - 3t, which matches the correct answer.

Which expression represents the perimeter, in units, of this trapezoid?

A. 17x + 25

B. 42x

C. 25x + 17

D. 17x - 25

Answer explanation

The perimeter of a trapezoid is the sum of all its sides. The expression 17x + 25 correctly represents this sum, making it the right choice. Other options do not accurately reflect the total length of the sides.

Which is equivalent to the expression below? 5b + 3 - 2b + 8

3b + 11

7b + 11

3b + 5

7b + 5

Answer explanation

To simplify the expression 5b + 3 - 2b + 8, combine like terms: (5b - 2b) + (3 + 8) = 3b + 11. Thus, the equivalent expression is 3b + 11.

Which is equivalent to the expression below? 2m + 5 + 4m + 7 + 2n

6m + 2n + 12

6m + 12n

8m + n + 12

14m + 2n

Answer explanation

Combine like terms: 2m + 4m = 6m, and 5 + 7 = 12. The term 2n remains unchanged. Thus, the expression simplifies to 6m + 2n + 12, which matches the first answer choice.

MULTIPLE CHOICE QUESTION

y + 3

Answer explanation

To find the equivalent expression, distribute \(\frac{2}{5}\) to both terms in \(y + 15\): \(\frac{2}{5}y + \frac{2}{5} \cdot 15 = \frac{2}{5}y + 6\). Thus, the correct choice is \(\frac{2}{5}y + 6\).
