The standard form would be x+3y=-27
Answer:
so 1/3 must be subtracted from the sum of 1/4 and 1/6 to have an average of 1/12 of all the two fractions.
Step-by-step explanation:
let the fraction be x
(1/4 + 1/6)-x = 1/12
or, 10/24 - x = 1/12
or, 5/12-1/12 = x
so, x = 4/12 = 1/3
Answer:
(x+6)^2 =0
Step-by-step explanation:
x^2+ 12x + 36 = 0
Subtract 36 from each side
x^2+ 12x + 36-36 = 0-36
x^2 +12x = -36
Take the coefficient of x
12
Divide by 2
12/2 =6
Square it
6^2 =36
Add this to each side
x^2+ 12x + 36 = -36+36
(x+12/2)^2 = 0
(x+6)^2 =0
