Use the distributive property to write an expression equivalent to 14x+21y

14x+21y = 7*2x + 7*3y = 7(2x+3y)

14x+21y = 7*2x + 7*3y = 7(2x+3y) is an incorrect answer.

However, the correct answer:
= 7(2x+3y+z)

9x + 2y - 3 - 2x - 2y

this does not help

Can you answer this? Use the Distributive property to write an expression equivalent to y(-3-8x)

I think this is the answer -3y -8yx

To use the distributive property to write an expression equivalent to 14x + 21y, we need to multiply each term in the expression by a common factor. In this case, the common factor is 7, which is a common factor of both 14 and 21.

By applying the distributive property, we can multiply the common factor to each term:
14x + 21y = (7 * 2x) + (7 * 3y) = 7(2x) + 7(3y)

Simplifying this expression gives us the equivalent expression:
14x + 21y = 7 * 2x + 7 * 3y = 7(2x + 3y)
