Answer:
$64.89
Step-by-step explanation:
57.68 + 1.25 × 57.68
= 57.68 + 72.1
= 129.78
The original price was $129.78.
129.78 – 0.50 × 129.78
= 129.78 – 64.89
= 64.89
The discount price was $64.89.
I would say the answer is 54(8)
How do you get from 3 meters to 5 meters? Add 2 meters. How do you get from 5 meters to the next measurement? Add 2 meters again.
Start at 3 meters, add 2 to get 5 meters, and so on. Continue this pattern until you have all 6 side lengths. The last one represents the length of the longest side.
Here we're working on an "arithmetic sequence."
Answer:

Step-by-step explanation:
The most common way to solve for the roots of a polynomial is to use the Quadratic formula, which will return us with two values of x that make the equation equal 0.
...however, this form of the equation is already in root form. If we multiplied these two terms, we'd get
, and when we factor that, we'd get -13 and 21.
Roots are usually written in the form
, where the zeroes will be the value of x that makes each binomial equal 0 - aka, the opposite of a and b.
The opposite of 13 is -13, and the opposite of -21 is 21.
Therefore, the solutions of this equation are -13 and 21.
