Use the distributive property to write the problem without parentheses: 4(2x + 11 - 8x + 36).

a) 4(2x) + 4(11) - 4(8x) + 4(36)
b) 8x + 44 - 32x + 144
c) 8x - 32x + 44 + 144
d) 4(2x + 11) - 4(8x + 36)

Final answer:

By using the distributive property, the expression 4(2x + 11 - 8x + 36) can be expanded to 8x + 44 - 32x + 144, which corresponds to option b).

Step-by-step explanation:

To use the distributive property to write the expression 4(2x + 11 - 8x + 36) without parentheses, we apply the property by multiplying each term inside the parentheses by 4.

The distributive property states that for any numbers a, b, and c, the equality a(b + c) = ab + ac holds true. Using this property, we can expand our expression:

• 4(2x) gives us 8x,

• 4(11) gives us 44,

• 4(-8x) gives us -32x (note the change in sign), and

• 4(36) gives us 144.

Combining all these results, we get the expanded expression: 8x + 44 - 32x + 144.

Therefore, the expression without parentheses, using the distributive property, is option b) 8x + 44 - 32x + 144.
