Parentheses can be eliminated using the distributive property
-6x +6(3x -4xy) = -6x +18x -24xy
Like terms (those with the variable x only) can be combined
x(-6+18) -24xy = 12x -24xy . . . . . simplified
_____
In some cases, you may be interested in factoring the expression. 12x is a common factor for the two terms, so another way to write this expression is
... 12x(1 -2y)
The area for this is
A= 7x9/2+3x9+9x6
= 31.5+27+54
= 112.5
Answer
2,6,10,14,18,22
Step-by-step explanation:
add 4
The answer is B; Take Ax + By = C and subtract the Ax to the other side
=
By = C-Ax
Now you divide by B to get y by itself.
y = (C-Ax)/B
This is assuming you accidentally left off parenthesis or the fraction bar because without one of either of those none of the answers would be right.
