Step by step solution to the polynomial equation (ײ - x + 5)(x - 3)​

Mathematics
1 answer:
denis23 [38]3 years ago
7 0

Answer:

There is no equals sign in that expression so it is not actually an equation and has no solution.

If you are looking to expand the two polynomials, then you get:

(x² - x + 5)(x - 3)

= x(x² - x + 5) - 3(x² - x + 5)

= x³ - x² + 5x - 3x² + 3x - 15

= x³ - 4x² + 8x - 15

The school chorus has 52 students which represents 26% of the seventh graders. How many students are in the seventh grade
barxatty [35]

Answer:

There are 200 students in the seventh grade.

Step-by-step explanation:

For equations like these, you have to use the is/of formula, which is:

Percent/100 = is/of.

Since you are trying to find how many students are in the seventh grade, this means that 52 <u><em>is</em></u> 26% of the total amount of students in the seventh grade. So, the formula would look like so:

26/100 = 52/n.

Next, you have to cross multiply, which means you would multiply 26 by n, and 52 by 100.

Then, you are going to have this left over from the cross multiplying:

5200 = 26n.

Divide 26 on both sides, leaving you with:

1n = 200, or n = 200.
