Which expression is not equivalent to the other three
a -9-7n+16n
b 9{n-9}
c n-9+8n
d 9n-9

no he doesnt because "-16' is negatiive

step-by-step explanation:

what’s the question?

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

the unknown side length of the golden rectangle with the given side length l = 9 is s = 5.56
