Question

Expand −5(2q + 8).

Answer 1

To expand -5(2q + 8), you need to distribute the -5 to both terms inside the parentheses.

Distributing -5 to 2q gives -5 * 2q = -10q.
Distributing -5 to 8 gives -5 * 8 = -40.

Therefore, -5(2q + 8) expands to -10q - 40.

Answer 2

Expand 7/10(5d+6).(1 point)

5d
+ 215
5 d + 21 fifths

35d + 42
35d + 42

72d + 215
72d + 215

35d + 6
35d + 6

Answer 3

To expand 7/10(5d + 6), you need to distribute 7/10 to both terms inside the parentheses.

Distributing 7/10 to 5d gives (7/10) * 5d = 35/10 * d = 3.5d.
Distributing 7/10 to 6 gives (7/10) * 6 = 42/10 = 4.2.

Therefore, 7/10(5d + 6) expands to 3.5d + 4.2.

Answer 4

Expand −5/8(3p+8).(1 point)
Responses

−15p + (−40)
−15p + (−40)

3p + 8
3p + 8

−158 p−5
−158 p−5

−158 + 3p

Answer 5

To expand -5/8(3p + 8), you need to distribute -5/8 to both terms inside the parentheses.

Distributing -5/8 to 3p gives (-5/8) * 3p = -15/8 * p = -15p/8.
Distributing -5/8 to 8 gives (-5/8) * 8 = -40/8 = -5.

Therefore, -5/8(3p + 8) expands to -15p/8 - 5.

Answer 6

Expand 5(y + 2) using the distributive property.(1 point)
Responses

5y + 2
5 y plus 2

6y + 7
6 y plus 7

5y + 10
5 y plus 10

6y + 10

Answer 7

To expand 5(y + 2) using the distributive property, you need to distribute the 5 to both terms inside the parentheses.

Distributing 5 to y gives 5 * y = 5y.
Distributing 5 to 2 gives 5 * 2 = 10.

Therefore, 5(y + 2) expands to 5y + 10.
