Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
The goal is to isolate x. For this equation, you need to distribute the -3 to the terms inside the parentheses first. Then, add both sides by 12. Finally, divide the 24 by -3 in order to finally isolate x.
Thus, x = -8.
Answer:
(x-4)=0 or (x+2)=0 is correct
Step-by-step explanation:
(x+1)(x-3)=5
x^2 -3x +x -3=5
x^2-2x-8=0
x^24x+2x-8=0
(x+2)(x-4)=0
so,
(x-4)=0 or (x+2)=0
One gallon and 1/30
add 1/3 + 1/5 + 1/2
find the common denominators. the common denominator is 30.
10/30 + 6/30 + 15/30. add and you get 31/30. which equals one gallon and 1/30
