Answer:
x = 
Step-by-step explanation:
Given
- 
= 
← factor denominator
- = 
[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]
Multiply through by x(x + 1)
4x² - 5(x + 1) = 4
4x² - 5x - 4 = 4 ( subtract 4 from both sides )
4x² - 5x - 9 = 0 ← in standard form
(x + 1)(4x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
4x - 9 = 0 ⇒ 4x = 9 ⇒ x =
However, x ≠ - 1 for reason given above, then
solution is x =
Answer:
1/3 or 3
Step-by-step explanation:
9-6 = 3
Answer:
Step-by-step explanation:
3x+3-8=36x-48
collect like terms
3x-36x=-48-3-8
-33x=-59
divide both side
-33×\+-33=-59/-33
×=59/-33 or 1.69
First, you need to find the length of each edge. So, you do 2 1/2*6 and 2 1/2*9.
After doing that, you get 15 for the left edge and 22.5 for the top edge. Finally, to find area, you do 15*22.5, which is our answer, 337.5 square inches.
Sorry if I'm wrong XD
ANSWER
EXPLANATION
The general term of the arithmetic sequence is
For the first term,we substitute
to get,
Similarly
The sum of the first n-terms is given by the formula,
where l is the last term.
In this case
We substitute these values to get,
We could have also used the formula,
