This is because none of the numbers can be divided by any number other than themselves or 1.
Answer:
(x - 5)(x + 3)
Step-by-step explanation:
to solve x² - 2x = 15, we need to get all the terms on one side so we can solve the quadratic equation using factoring. to do this, we subtract 15 from both sides
x² - 2x = 15
- 15 -15
x² - 2x - 15 = 0
now we can factor. we need 2 numbers that when multiplied together give us -15, and when those 2 numbers are added together we get -2
because we have a -15, we can assume that one number must be negative and the other positive, as a negative times a postive is a negative.
we can use 3 and -5 as factors and test it out. we put x in front because we have an x²
(x - 5)(x + 3) < we can FOIL to check to see if this is correct. its not mandatory to check but when you arent sure of the answer you can FOIL it out
FOIL stands for: First, Outside, Inside, and Last terms
F: (x - 5)(x + 3) = x²
O: (x - 5)(x + 3) = -3x
I: (x - 5)(x + 3) = 5x
L: (x - 5)(x + 3) = -15
x² + 3x - 5x - 15 < subtract 3x from 5x
x² - 2x - 15
this checks out, so our answer is (x - 5)(x + 3)
Um. i’m pretty sure it’s just 30 feet
Answer:
$
Step-by-step explanation:
<em>To find out what she paid with the discount and no tax, turn the percentage into a decimal. To do that, divide it by 100.</em>
Then, multiply that by the total.
<em>Subtract that by the total.</em>
<em>Now, we need to find the sales tax. Again, we know to divide the percentage by 100 to get the decimal. In that case, 6.5% is now .065.</em>
Multiply that by the discounted price.
<em>Add that to the price.</em>
$
would be the total price.
