The answer to that problem is A
Don't forget the invisble negative ones to distriute
do inside to outside
{n-1-1[n-1-1(n-1)]}
do inside
{n-1-1[n-1-n+1]}
simplify inner parenthasees
{n-1-1[n-n+1-1]}
{n-1-1[0]}
multply
{n-1-0}
add
n-1-0=n-1
it is n-1 simplified
-3x² + 3y² + 4x + 4x² - 4y + 2
Add like terms.
x² + 3y² + 4x - 4y + 2
So the answer is D.
The equation for this is .09x=.34
so just divide .34 by .09
and get X=3.77 repeating
Hope this helps! :D
Answer: D
Each time a new row and a new column is added. The last pattern had 3 rows and 4 columns, so the next pattern will have 4 rows and 5 column.
