7x/x-4 * x/x+7
mutiply the numerators together
(7x)(x)= 7x^ 2
mutiply the denominators together
(x-4)(x+7)
(x)(x)(7)(x)= x^2+7x
(-4)(x)(-4)(7)= -4x-28
x^2+7x-4x-28
x^2+3x-28
Answer:
7x^2/x^ 2+3x-28
In order to do these, simply translate the sentence mathematically.
1) x-15=7
2)3x+4=13
3)x+x+2+x+4=51
Hope this helped :D. Comment below if you have any questions!
Answer:
The function which represents this sequence will be:

Hence, option (A) is true.
Step-by-step explanation:
Given the sequence

An arithmetic sequence has a constant difference 'd' and is defined by

computing the differences of all the adjacent terms

As the difference is the same, so

as

Thus, substituting
,
in the nth term of an arithmetic sequence



Therefore, the function which represents this sequence will be:

Hence, option (A) is true.
Answer:
V≈113.1
Step-by-step explanation:
