The triangles area would be 3 x 4 = 12 / 2 = 6.
The perimeter would be 12.

Perimeter would be 3+4+5 which is 12ft. Area would be base x height divided by 2. So 3x4 divided by 2 is 6ft.

Combining the like-terms, the result of the addition of polynomials f(x) and g(x) is given by:

f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}

<h3>How do we add polynomials?</h3>

We add polynomials combining the like-terms, that is, adding terms with the same exponent.

In this problem, the polynomials are:

  • f(x) = 3x^{\frac{1}{2}} + 7x^{-\frac{1}{4}} + 8x^{-4}
  • g(x) = -\frac{7}{4}x^{\frac{1}{2}} + 12x^{-\frac{1}{4}} - 21x^3

Combining the like terms, the addition is given by:

f(x) + g(x) = \left(3 - \frac{7}{4}\right)x^{\frac{1}{2}} + (7 + 12)x^{-\frac{1}{4}} + 8x^{-4} + 21x^3

f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}

How do you write 4540 million in standard form?
vovangra [49]
For this case what we should do is take into account the following conversion:
 million = 10 ^ 6&#10;
 We then have the following number:
 4540 million&#10;
 Applying the given conversion we have:
 4540 * 10 ^ 6&#10;
 By doing the corresponding calculation we have that the standard form is given by:
 4540 * 10 ^ 6 = 4,540,000,000&#10;
 Answer:
 
4540 million in standard form is:
 
4,540,000,000
