Given the following system, what would be the best way to start slowing the system?
dusya [7]
A would be the correct answer because the y variable only has a coefficient of 1. So we would solve for y, which would get us y=3x+5, then we would substitute the value in the second equation which would look like -4x+5(3x+5)=58. Hope this helpss. :)

Which are steps the could be used to slove 0=9(x2+6x)-18 by completing the square
Elis [28]

Answer:

(x+3)²-11=0

Step-by-step explanation:

0=9(x2+6x)-18

0= 9x² +54x-18

0= 9( x²+6x-2)    taking 9 common

0= x² +6x-2 (breaking the mid term to find the second element of the square

0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element

0= (x+3)² -11 summing up

I am not sure what it is asking, but if this is what you were asking for here it is. Surface area is harder to explain, but volume is multiply all dimensions.

Hope this is what it was asking!
