Remark
My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)
What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.
zero
n = 0
g(0) = 34 - 5*0
g(0) = 34
One
n = 1
g(1) = 34 - 5*1
g(1) = 34 - 5
g(1) = 29
Two
g(2) = 34 - 5*2
g(2) = 34 - 10
g(2) = 24
Three
g(3) = 34 - 5*3
g(3) = 34 - 15
g(3) = 19
Four
g(4) = 34 - 5*4
g(4) = 34 - 20
g(4) = 19

Answer:
Total length of iron needed to make the square frame and two diagonals = 43.44 in (Approx)
Step-by-step explanation:
Given:
Length of diagonal = 9 in
Find:
Total length of iron needed to make the square frame and two diagonals.
Computation:
Area of square = 1/2(diagonal)²
Area of square = 1/2(9)²
Area of square = 40.5 in²
Area of square = Side × Side
40.5 in² = Side × Side
Side = 6.36 (approx)
Total length of iron needed to make the square frame and two diagonals = Permeter of square + (2 × diagonal)
⇒ (4 × 6.36) + (2 × 9)
⇒ (25.44) + (18)
⇒ 43.44 in
Total length of iron needed to make the square frame and two diagonals = 43.44 in (Approx)
So first you want to find how much the second car gains on the first car in one hour.
Since the second car travels 65 kph, but the first travels 40, we can just subtract 40 from 65 to find how much faster the second car is than the first.
65 - 40 = 25
So the second car is 25 kph faster than the first.
Since the first car had a 2 hour head start, we first want to calculate how far away the first car got from the sign before the second car reached the sign.
So just 2 hours * 40 kph, which gives you 80 kilometers.
So now we know the second car has to gain 80 km on the first car in order to overtake it.
Since the second car gains 25 km per hour on the first car, we can just divide 80 by 25.
80 / 25 = 16/5, or in decimal form 3.2.
So the second car will overtake the first car in 3.2 hours, or 192 minutes, which is also 3 hours and 12 minutes.
You have to do mutiplication. how do you know that you have to do mutiplcation because the (of) it means times. so 26 * 2.21 = 0.5746
2.21/x=100/26
<span>(2.21/x)*x=(100/26)*x </span>
<span>2.21=3.8461538461538*x
</span>(3.8461538461538) to get x
<span>2.21/3.8461538461538=x </span>
<span>0.5746=x </span>
<span>x=0.5746</span>
