We can factorise this expression by grouping. First let us arrange it in this way
Let us bracket them like this:
In the first bracket portion, take x as common and in the second expression, take 2 as common.

Answer:
it is an improper fraction
Step-by-step explanation: mixed=5 2/3 is the mixed fraction
Answer:
A) x + y = 8
B) 3x + 2y = 21
We multiply A) by -2
A) -2x -2y = -16 Then we add this to
B) 3x + 2y = 21
x = 5
y = 3
Second answer is correct
Step-by-step explanation:
the formula is a_{1}+(n-1) d
so a_{1} would be the first number in the sequence, which would be 13 in problem 9.
13+(n-1)d
then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)
13+(10-1)d
then you find the difference between each number, represented by d which in this case is 3
13+(10-1)3
13+(9)3
13+27=
40
