What value of x in the solution set of 2x-3 is greater than 11-5×​
Salsk061 [2.6K]

Answer:

the value of x if that's what you mean is 2 because first you add 3 from both sides and your new equation should be 2x>14-5×, then you add 5x from both sides and your new equation should be 7x>14. After that you divide 14 by 7 and your final answer will be x=2 or 2

Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial
Readme [11.4K]

Answer:

Result after multiplication of polynomial is: 6x^3+13x^2-5x

Degree of polynomial = 3

Step-by-step explanation:

The given polynomials are:

x(3x-1)(2x+5)

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.

So, multiplying the polynomials in round brackets first

=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)

Now multiplying with x

= 6x^3+13x^2-5x

Degree of a polynomial is the highest exponent of variable in the polynomial.

In the acquired result, the highest exponent of x is 3 so the degree is 3.

Hence,

Result after multiplication of polynomial is: 6x^3+13x^2-5x

Degree of polynomial = 3

How many of the positive divisors of 2160 are multiples of 3?
TEA [102]
30 of the divisors are multiples of 3

The factors of 2160 are 1, 2160, 2, 1080, 3, 720, 4, 540, 5, 432, 6, 360, 8, 270, 9, 240, 10, 216, 12, 180, 15, 154, 16, 135, 18, 120, 20, 108, 24, 90, 27, 80, 30, 72, 36, 60, 40, 54, 45, 48
These are all divisors of 2160 but only 30 are multiples of 3.
The ones that are NOT are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80

You can also do this using prime factors 2x2x2x2x3x3x3x5 = 2160 but it is harder to explain.
