Answer:
Step-by-step explanation:
just multiply the too nubers u have and thats ur answer
The rules for the signs of quotients are the same as the rules for the signs of products.
We presume you want to find the number.
Let n represent the number.
6 + n/4 = 3 . . . . . . . 6 more than the quotient of a number and 4 is 3.
To solve this, we "undo" what is done to the number. First we undo the addition of 6 by adding its opposite, -6. We add -6 to both sides of the equation so the equal sign remains valid.
6 -6 +n/4 = 3 -6
n/4 = -3 . . . . . . . . simplify
Now, we need to undo the division by 4. We do that by multiplying by 4. Again, we must do that to both sides of the equation so the equal sign remains valid.
4(n/4) = 4(-3)
n(4/4) = -12
n = -12
The number is -12.
(2x + 1)(x - 5)
Simplify this by using the rainbow tactic. :)
(2x · x) + (2x · -5) + (1 · x) + (1 · -5)
Simplify!
(2x²) + (-10x) + (x) + (-5)
Get rid of the parenthesis.
** Remember : a negative times a positive is always a negative, and a negative times a negative is always a positive. **
2x² - 10x + x - 5
Add like terms.
2x² + (-10x + x) - 5
Since "-10x" & "x" have the same variable, we can simplify this.
Simplify.
2x² + (-9x) - 5
Get rid of parenthesis.
2x² - 9x - 5
