There is no symbol before 2(7y-16).

y2 + 8y + 16 = y2 + 4y + 4y + 16 = y(y + 4) + 4(y + 4) = (y + 4)(y + 4) or (y + 4)2
x = y - 4 when x = 16, the equation becomes 16 = y - 4 so that y = 20
y=6x-16 y=-2x+8
Let the two numbers be x and y since their sum is 16 x+y=16 since their difference is 20 x-y=20 so since x+y=16 x=16-y and now plug this in below 16-y-y=20 and 16-2y=20 -2y=4 y=-2 and x-2=16 so x=18 the numbers are 18 and -2
Yx7y = 7y2 (squared )
(y + 27)(y^2 - 27y + 729)
It is: 3y and y
7 y - 4 + y + 5 = 287 y + y + 1 = 288 y + 1 = 288 y = 27y = 27/8y = 3.375
Since 27y is a factor of 54y3, it is automatically the GCF.
Since 27y is a factor of 54y3, it is automatically the GCF
Since 54y3 is a multiple of 27y, it is automatically the LCM.
It depends on where there are parentheses, if there are any. y + 33 + 2/4 = y + 27.5 (y+3)3 + 2/4 = y3 + 9y2 + 27y + 27.5

2(7y + 14y - 27y)or you could just total them-1 x 2 x 2 x 3 x y = -12y
