Answer:
A
Step-by-step explanation:
if these are fractions than its A.
2x-4=2
4x-5=5/4
6 + 2n > 12 |subtract 6 from both sides
2n > 6 |divide both sides by 2
n > 3
I dont really know how to do the work but i guess 1/125 is the simplest from to do 0.008 into a fraction
Answer:
468
Step-by-step explanation:
Set it up like the following-
18
26
--------
108
360
--------
408
Take the right number (6) and multiply it with 18
6 x 18 = 108
Now do the same with 2, except put a 0 at the end
2 x 18 = 36
add 0
360
Add both numbers-
360 + 108 = 468
First you open 2 parenthesis with x in each one:
(x )(x )=0
Then, you place the sign of the second term (the x term) in the first parenthesis.
(x+ )(x )=0
Next, you multiply the signs of the x term and the sign of the constant (the third term).
Since + × - = -, then you place a -.
(x+ )(x- )=0
You look at the constant (-18) and the second term (3). What two numbers multiplied give you -18 but subtracted (since the signs inside the parenthesis are opposite) give you 3? Those numbers are 6 and 3.
Since the result of the substraction need to be 3, you place the 6 with the + sign and the 3 with the negative sign (if you think of it, 6-3=3 but 3-6 = -3. That's the reason behind placing the numbers)
(x+6)(x-3)=0
Therefore,
x+6=0 or x-3=0
x=-6 or x=3
Your roots are -6 and 3.
