The answer you are looking for is -3.
To find this answer, you must get "n" by itself. First subtract 5 from both sides. You would get (-8)n = 24, which you then divide -8 on both sides, to get a final answer of n = -3.
I hope this helps!
Answer: AD = 9cm
Step-by-step explanation: This is a 30-60-90 triangle, so the hypotenuse is equal to twice the length of the short side of the right angle.
BC is the short side of the large triangle, so AB, the hypotenuse of the large triangle is 2×6, 12 cm
BC is also the hypotenuse of the small triangle, ΔBCD, so it is twice the length of BD, to that makes BD = 6/2= 3
Subtract BD from AB.
That's 12 - 3 = 9 the length of AD
4. is correct
5. A is correct
6. B is correct
Answer:
only (2) and (4) are polynomial out of given options.
Step-by-step explanation:
Polynomial is an expression having variables having positive integer exponents with real constant coefficients. example
We are given some polynomials and we have to choose whether are polynomial or not.
Consider ,
1)
Since, Polynomial does not have a fractional exponent.
So, 1) Not a polynomial.
2)
Since all of the variables have integer exponents that are positive this is a polynomial.
3)
Not a polynomial because a term has a negative exponent
.
4)
Since all of the variables have integer exponents that are positive this is a polynomial.
Thus, only (2) and (4) are polynomial out of given options.
