11/12 because it is more than 1/2 (which is what 4/8 simplifies to!)
Answer:
7x + 20 or 20 + 7x
Step-by-step explanation:
2(5 + 3x) + (x + 10)
=> Multiply the parenthatic values in the first parenthesis by 2
(10 + 6x) + (x + 10)
=> Now add similar values
20 + 7x
Hope this helps!
Answer:
x=2 x=-2
Step-by-step explanation:
x² + 2x - 4 = 2x
Subtract 2x from each side
x² + 2x-2x - 4 = 2x-2x
x^2 -4 = 0
Factor
We know this is the difference of squares
(x-2)(x+2) =0
Using the zero product property
x-2 =0 x+2 =0
x=2 x=-2
