1st: do distributive property, that will give you 3x + 6 + 5x

2nd: combine like terms to simplify, this will give you 6 + 8x

12 bouquets.
12 is the only number that is divisible by 24, 60, and 84. So that is your only option.

Suppose you received a job offer with a starting salary of $48,500 per year and a guaranteed raise of $1200 per year. Find the n

LuckyWell [14K]

Answer:

7 years

Step-by-step explanation:

This is going to be an arithmetic progression:

48500, 48500 + 1200, 48500 + 1200*2, ...

So the first term is

a₁ = 48500

and the common difference is

d = 1200

Sum of AP is:

S = (a₁ + aₙ)*n/2 = (2a₁ + (n - 1)d)*n/2

Substitute and solve for n:

(2*48500 + (n - 1)*1200)*n/2 = 321000
(97000 + 1200n - 1200)n = 642000
1200n² + 95800n - 642000 = 0
6n² + 479n - 3210 = 0

Solving we get a positive root of:

n ≈ 6.21 and it rounds up to 7 years

Answer:

$\binom{6}{2} = a_{0}=15$

Step-by-step explanation:

$\binom{6}{2} = a_{0}$

$\binom{n}{r} =\frac{n!}{r!\times(n-r)!}$

It is representing a combination form where, n is number of items we have and r is the number of items we choose from n

Here, n = 6 , r = 2

$\binom{6}{2} =\frac{6!}{2!\times(6-2)!}$

= $=\frac{6!}{2!\times(4)!}$

$n!=n\times(n-1)\times(n-2)\times(n-3).....\times3\times2\times1$

$=\frac{6\times5\times4!}{2\times(4)!}$

$=\frac{6\times5}{2}$

$={3\times5}$

$={15}=a_0$

Thus, $\binom{6}{2} = a_{0}=15$
