Answer:
No, it is incorrect.
Step-by-step explanation:
The quadratic equation is
or
. To complete square we take the coefficient of x divided by 2, square that value and add the result to both sides. In the equation given the number to do the process is 20, not 6, then the solution method is incorect.

Answer:
x=1
Step-by-step explanation:
5x+2=3x+4(2x-1)
First take the ( ) 4*2xand 4*-1
Then simplify and add all like terms
then subtract/add(opposite of what it is) whichever x term from both sides
then subtract/add the numbers on the side you chose to the other side to get something as the following
x=#
then divide x by the #
if you are looking for.... 2(B-4)= (6)b
2b - 8 = 6b
2b - 6b= 8
-4b=8
so b= -2
the question is b-4 divided by 6 equals b/2
Answer:
8 cups of blue and 12 cups of red
Step-by-step explanation:
Combine 1/3 c of blue + 1/2 c of red = 5/6 c of purple.
(5/6)x = 20
x = (6/5)20 = 24
this is applied to each of the above measurements to show that you need 8 c of blue + 12 c of red.
