Using the combination formula, it is found that the probability that you and your 3 friends will get to sit together in the same row is given by:
.
We do not consider the order, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

4 students will be taken from a set of 27, hence the number of ways they can sit is given by:

Only one outcome is desired, hence the probability is given by:
.

Step-by-step explanation:
I= (4 + x ) * 5 E= x
I: 52 more than Emma
(4+x) * 5 = x + 52
20 + 5x = x + 52
5x - x = 52 - 20
4x = 32
x = 8
so then
E= 8
I= 12 × 5 = 60
Step-by-step explanation:
From the looks of it, it seems that you're factoring out the greatest common factor. I gotcha covered.
The square boxes are the biggest common factors in those equations. Hopefully, this helps!
Im not fully correct but i think you just multiply 3 x7= 21
The given trinomial can be factored using factorization as
x²+19x+84
=x²+12x+7x+84
=x(x+12)+7(x+12)
=(x+12)(x+7)
Thus x+12 and x+7 are the factors of the given trinomial. From these we can see x+12 is listed in option A.
So the answer to this question is Option A
