We suspect that the questioner isn't quite sure of what the question is,
so we may be going off in a direction other than what he intended.
We're going to look for the value of 'Y' that makes the statement true.
Y + (6 - 28) = 40
Y - 22 = 40
Add 22 to each side:
Y = 62
Y = 62
-3.32
20
Do you mean: y2+13y+40 = 0 If so then when factored: (y+5)(y+8) = 0 Therefore: y = -5 and y = -8.
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
x + y = 17 + 23 = 40
Y = 10x 10x = 40 y = 40
40 + 60 = 60 + x Addition has a property called the Commutative property which says that: x + y = y + x. So, over here: x = 40 y = 60 Thus, 40 + 60 = 60 + 40
y=16 x= -4
(6, 40) and (-1, 5)
4y
y=84-72=12 z=84-52=32 x=84-12-32=40
