Area: 20 x 30 so 600
perimeter: 20 + 20 + 30 + 30 = 100
-6x -(3x)
Pretend that there is a -1 in front of the bracket
-6x-1(3x)
mutiply the bracket by -1
(-1)(3x)= -3x
-6x-3x= -9x
Answer: -9x
I think it’s y= -2/2x +2? Something like that I may be wrong lolz
<span>When creating a subset of 5 elements from 7 elements, order should not matter. Therefore, we use the combination formula over the permutation formula.
The combination formula given n elements total and r elements used is n! / [r!*(n-r)!]. Substituting 7 for n and 5 for r, we get:
7! / (5!*2!) = 7*6 / 2 = 21
21 subsets can be created</span>
You can factorize to simplify the expression
The answer would be,
Hope this helped
:D
