Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions? When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.

The answer is choice first which is "When x = 3, both expressions have a value of 30".

Step-by-step explanation:

Given:

First expression:

Second expression:

Through the question when we substitute x=3 into its first equation so we get:

The value will be substituted by x=3 into its second expression:

So, it will prove that both the two expressions are equivalent.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
