B. Right (they are 90° angles)
D. Adjacent (they share sides)
G. Supplementary (the total of the 2 angles is 180°)
Y=16x²/9 ....................................
In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient.
In this problem the co-efficient of x =
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
, assuming they mean pre eat values.
