Answer:
an = 39 +4(n -1)
Step-by-step explanation:
The formula for the general term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, the sequence has first term a1 = 39 and common difference d = 43-39 = 4. So, the general term is ...
an = 39 +4(n -1)
Answer:
u cant make it into simplest form
Step-by-step explanation:
the equation is false
Answer:
x = 0 or x = 1
Step-by-step explanation:
Given equation:

Multiply the two denominators to get the same denominator:
Multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator of the first fraction.
Multiply the numerator of the second fraction by the denominator of the first fraction to get the new numerator of the second fraction.

Add the numerators and keep the denominator so that there is now one fraction:

Simplify the numerator by expanding the brackets:


Simplify the denominator by expanding the brackets:

Multiply both sides by the denominator of the left side:

Simplify and move everything to the left side:


Factor:

Therefore:


Therefore, x = 0 or x = 1
the third option
because 1/3 is not equal to three
where as if we replace the x with one in all the other we would find that the equation is correct.
