group the like terms

3x+x-6x-13+4=12

Answer:

Step-by-step explanation:

3x + x - 13 + 4 - 6x = 12

we try to combine the elements with the same power of x (including the ones without any x) :

3x + x - 6x

-13 + 4

so, we get

-2x - 9 = 12

-2x = 21

x = -21/2

Which point lies on the graph of the finite sequence shown?<br> 5, –1, 6, 0, 7, 1, 8

djyliett [7]

Hello,

$u_{1} =5\\
 u_{2} = u_{1}-6=5-6=-1\\
 u_{3} = u_{2}+7=-1+7=6\\
 u_{4} = u_{3}-6=6-6=0\\
 u_{5} = u_{4}+7=0+7=7\\
 u_{6} = u_{5}-6=7-6=1\\
 u_{7} = u_{6}+7=1+7=8\\
...\\

\boxed{ u_{2n} = u_{2n-1}-6}\\\\

\boxed{ u_{2n+1} = u_{2n}+7}\\

(3ab+2c)^3 what is the answer

svet-max [94.6K]

Answer:

$=27a^3b^3+54a^2b^2c+36abc^2+8c^3$

Step-by-step explanation:

$(3ab+2c)^3$

$=(3ab+2c)$ × $(3ab+2c)$ ×

$=(3ab+2c)(9a^2b^2+12abc+4c^2)$

$=(3ab)(9a^2b^2)+(3ab)(12abc)+(3ab)(4c^2)+(2c)(9a^2b^2)+(2c)(12abc)+(2c)(4c^2)$

$=27a^3b^3+36a^2b^2c+12abc^2+18a^2b^2c+24abc^2+8c^3$

$=27a^3b^3+54a^2b^2c+36abc^2+8c^3$
