Question

(3r^4-2r^3+2r^2+12r-6)+(r^5+6r^3+7r^2+12r-6)+(r^5+6r^3+7r^2-2r+4)+(-6r^4+r^2-8r-10)

Answer 1

no it doesn't

Answer 2

"no it doesn't"
lol

Answer 3

LOL.

Answer 4

Im glad that you all find me amusing....but I can do with without the laughter.

Answer 5

We just have to add like terms,
x^4 with x^4,
x^3 with x^3 and so on,

Therefore,

\[r^ 5 - 3r^4 +10r^3 + 17r^2+14r -1 8\]

Answer 6

and with all the laughter, the answer key indicates that you are wrong.

Answer 7

are u sure the question you typed is correct? o_O

Answer 8

of course

Answer 9

i can bet im correct.

Answer 10

you guys missed a " r^5 "
\[\rightarrow 2r^{5}-3r^{4}+10r^{3}+17r^{2}+14r-18\]
@mslorraine no disrespect intended, the bluntness in which you said it made me think of something else

Answer 11

find the variation constant and equation of variation where y varies directly as x and y=20 when x=20

Answer 12

y= kx
--> k = y/x = 20/20 = 1

y = x
