Theyre all correct
Step-by-step explanation:
Answer: 12x + 15y
Explanation:
1. 3 x 4x + 3 x 5y
2. 12x + 15y
This expression can not be expanded further because there are no like terms.
Hope this helps :)
s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
Given:
The two functions are:
To find:
The . Assume .
Solution:
We have,
Now,
Therefore, the correct option is A.
