Which expressions are equivalent when m=1 and m=4? (picture attached)
2 answers:
Answer:
Option 2 is correct.
Step-by-step explanation:
Given the expressions
we have to choose the option for which the expressions are equivalent when m=1 and m=4.
The substitution of values shown in table in attachment.
The only option 2 which gives the same values for m=1 and m=4 in both the expressions.
∴ Option 2 is correct.

Hi there!
In order to fin the average, you need to add all the terms together and then divide the result by the number of terms :
() ÷ 2 = average
Now, I’m assuming that you know that in order to add fractions, both fractions must have the same denominator (bottom number in a fraction). Since these fractions do not have the same denominator, we must give them one.
To find the lowest common denominator (which will help us solve this problem), we must find out what 2 & 3 go into. Well, both numbers go into 6!
So, if the denominator is now 6, you must multiply the numerator (numbers about the “/” line in this case are both 1) by how much you multiplied its denominator by.
For 1/2, you multiplied 2 by 3 to get 6. Therefore, you must multiply the 1 by 3 aswell.
for 1/3, you multiplied 3 by 2 to get 6. Therefore, you must multiply the 1 by 2.
and now you have 3/6+2/6 since the denominators are the same, you can add the numerators normally which gives you 5/6
÷ 2 =
Your answer is :
There you go! I really hope this helped, if there's anything just let me know! :)
