Answer with Step-by-step explanation:

we have to calculate the factors of the polynomial:

  6x^2 + 30x - 36

This could also be written as:

6(x^2+5x-6)\\\\=6(x^2+6x-x-6)\\\\=6(x(x+6)-1(x+6))\\\\=2\times 3\times (x-1)(x+6)

Hence, the factors of the polynomial   6x^2 + 30x - 36 are:

x-1,x+6,2,3

Hence, the correct options are:

1. x-1

3. 2

4. 3

5. x+6

Answer:

The expression is 10t = 65

Step-by-step explanation:

At the point where the local train and the express train meet, both trains would have travelled an equal distance.

A local train leaves the station in Springfield traveling toward New York City at a constant rate of 55 mph.

Let t represent the time it spent in travelling a given distance.

Distance = speed × time

Therefore,

Distance travelled by the local train is 55 × t = 55t

The express train headed for New York City on the same route leaves the station 1 hour later. The rate of the express train is 65 mph. It means that total time spent travelling the same distance as the local train is t - 1

Therefore, distance travelled is

65(t - 1)

Since the distance travelled is the same, therefore,

55t = 65t - 65

65t - 55t = 65

10t = 65

For the sequence <img src="https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%202n%2F%28n%2B1%29" id="TexFormula1" title="a_{n} = 2n/(n+1)"
Nat2105 [25]

Answer:

a_{10}=\frac{20}{11}


Step-by-step explanation:

The formula for nth term of a the sequence is given as  a_n=\frac{2n}{n+1}


<u>Finding the 10th term means finding  a_{10}, which means to plug in 10 into n, in the nth term formula.</u>

a_{10}=\frac{2(10)}{(10)+1}=\frac{20}{11}
