Answer:

250

Step-by-step explanation:

Since you are looking for the amount of shirts he had you will need to divide 25 by .10 or just multiply by 10.

Set up an equal proprtion. 25/x = 10/100 because 25 is 10% of the number you're looking for, or x. 25* 100 = 10x → 2500 = 10x → 250 = x. Uncle Percy started with 250 t-shirts.

Which of the following shows that polynomials are closed under subtraction when two polynomials, (5x2 + 3x + 4) − (2x2 + 5x − 1)
GuDViN [60]

Answer:

3x² - 2x + 5 ; will be a polynomial ⇒ answer A

Step-by-step explanation:

* Lets explain what is the polynomial

- A polynomial is an expression containing two or more algebraic terms.

- Polynomial is often the sum of some terms containing different powers

 of variables.  

- If you add or subtract polynomials, you get another polynomial.

- If you multiply polynomials, you get another polynomial.

* Lets solve the problem

∵ 5x² + 3x + 4 is polynomial

∵ 2x² + 5x - 1 is polynomial

- When we subtract them the answer will be polynomial

∵ (5x² + 3x + 4) - (2x² + 5x - 1)

- Open the second bracket by multiplying the negative sign by

  each term in the bracket

∵ -(2x²) = -2x²

∵ -(5x) = -5x

∵ -(-1) = 1

∴ (5x² + 3x + 4) - (2x² + 5x - 1) = 5x² + 3x + 4 - 2x² - 5x + 1

- Add the like terms

∴ (5x² - 2x²) = 3x²

∴ (3x - 5x) = -2x

∵ (4 + 1) = 5

∴ (5x² + 3x + 4) - (2x² + 5x - 1) = 3x² - 2x + 5

∴ 3x² - 2x + 5 is a polynomial

∴ (5x² + 3x + 4) - (2x² + 5x - 1) = 3x² - 2x + 5 ; will be a polynomial

* The answer is A

If s^2– 4s – 6 = 6, What are the possible values of s?
Effectus [21]

Answer:

s = +6 or -2

Step-by-step explanation:

{s}^{2}  - 4s - 6 = 6

=  >  {s}^{2}  - 4s - 6 - 6 = 0

=  >  {s}^{2}  - 4s - 12 = 0

Lets factorise the eqn.

=  >  {s}^{2}  - 6s + 2s - 12 = 0

=  > s(s - 6) + 2(s - 6) = 0

=  > (s - 6)(s + 2) = 0

Here 's' will have 2 values.

1) s - 6 = 0

=  > s = 6

2) s + 2 = 0

=  > s =  - 2
