Final answer: B
The simplest form of the function will be given by:
<span>n^2+3n+2/n^2+7n+10 - 2n/n+5
=[(n+1)(n+2)]/[(n+5)(n+2)]-2n/(n+5)
=(n+1)/(n+5)-2n/(n+5)
=[n+1-2n]/(n+5)
=(1-n)/(n+5)
Answer: </span>(1-n)/(n+5)
Answer:
Option B
Step-by-step explanation:
By using geometric mean theorem in the given right angle triangle RST,
ST² = 10.2 × 14.3
ST = 
ST = 12.077
ST ≈ 12.1
Therefore, Option B will be the correct option.
The first one is X, then the second one would be X+1 ( adding one, makes it consecutive).
Now you have X + X+1 = 667
Simplify:
2x +1 = 667
Subtract 1 from each side:
2x = 666
Divide both sides by 2:
x = 666 /2
x = 333
The first marker is 333
The second marker = 333 +1 = 334
Remark
Forget the Gamestop. I'd never use it. This one is on the house.
Solution
2.5(10 - x) + 10 = 72 - 1.5x*(5x + 12) The first step is to remove the brackets. Be very careful you understand the bracket on the right.
25 - 2.5x + 10 = 72 - 7.5x - 18 Study the signs carefully. Collect like terms.
35 - 2.5x = 54 - 7.5x Add 7.5x to both sides.
35 - 2.5x + 7.5x = 54 - 7.5x + 7.5x
35 + 5x = 54 Subtract 35 from both sides.
5x = 19 Divide by 5
x = 19/5
x = 3 4/5 = 3.8
Check
When you numbers are so cumbersome, you should check the answer.
<em><u>LHS</u></em>
2.5(10 - 3.8) + 10
2.5(6.2) + 10
15.5 + 10
25.5
<em><u>RHS</u></em>
72 - 1.5(5*3.8 +12)
72 - 1.5(19 + 12)
72 - 1.5(31)
72 - 46.5
25.5
<em><u>RHS = LHS</u></em> The solution checks.
