(y2+13y+22)/(y+2) = (y+11)
If you mean: 4y^2 +3 -13y then the expression is (4y-1)(y-3) when factored
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8
It can be simplified to: 12x-3w+13y
13y+3z+8
(y2+13y+22)/(y+2) = (y+11)
If you mean: 4y^2 +3 -13y then the expression is (4y-1)(y-3) when factored
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8
It can be simplified to: 12x-3w+13y
13y+3z+8
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
a) 4x+13y=40 b) 4x+3y=-40c) multiply b per(-1)=-4x-3y-40d) sum a and c: 4x+13y-4x-3y=40-(-40)=>10y=80 => y=8to find x replace y per its value in a or b and get x=-16
The way that this problem is written, it appears to be simple multiplication. What it is missing are the necessary parentheses to make the problem workable. Thought: 2yy 3 might be written as: (2yy)3 or 3(2yy) In either case, if this is the correct way of writing the problem, the answer is 6y to the second power. Diane White Oviedo, Florida Math teacher
(x - 13y)(x + 13y)
5y - 4 + 9y - 1y + 15= 5y + 9y - 1y + 15 - 4= (5 + 9 - 1)y + (15 - 4)= 13y + 9
