Take x= -6 and y=4 find i) x+y,
ii) (x-y ) –x
iii) x 2 + y 2 +2xy

I) -2

ii) -60

III) 4

Step-by-step explanation:

i) x+y = -6+4=-2

ii) (x-y)-x = (-6-4)-(-6)= -60

III) x^2+y^2+2xy = (-6)^2+4^2+2(-6)(4)= 4

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
