Question

A student attempted to generate an equivalent expression using the distributive property, as shown below: 5(x − 1) = 5x − 1 What was the mistake made? (1 point) 5 was not multiplied by x Incorrect sign was used for the first term 5 was not multiplied by −1 Incorrect sign was used for the second term

Answer 1

the correct answer must be 5x - 5 not 5x - 1

Explanation:

when we have a question such as 5(x - 1)

we must multiply both the numbers by 5

so we get 5 X x and 5 X -1

so it will be 5x - 5 which is the answer.
