Question

A student attempted to generate an equivalent expression using the distributive property, as shown below: 4(x + 2) = x + 8
What was the mistake made?
4 was not multiplied by x
4 was not multiplied by 2
Incorrect sign was used for the first term
Incorrect sign was used for the second term

Answer 1

Answer:

4 was not multiplied by x .

Step-by-step explanation:

If 4 will be multiplied by x then,

[4(x+2)] will not be equal to [x+8]

And if 4 will not be multiplied by x then,

[x+(4*2)]=[x+8]

x+8=x+8

Therefore, 4 must not be multiplied by x.
