Answer:
(a) 
(b) nth term: 
Step-by-step explanation:
Solving (a)
Given
The first 3 terms.
When n = 1
When n = 2
When n = 3
So, the first three terms are:
Solving (b)
Given

The nth term
The sequence is arithmetic.
So, first calculate the common difference (d)
The nth term is then calculated as:

Answer:
57kg
Step-by-step explanation:
We need to find the length of each piece of metal:
We already know that 2 of them are 6m and 8m and this would be the same for the pieces of metal opposite.
So we have four lengths - 6m, 6m, 8m, and 8m
To find the last length, we need to use pythagoras theory
a² + b² = c² where c is the slanted side, or the diagonal
6² + 8² = c²
36 + 64 = 100
c² = 100
c = √100 = 10
So the five lengths are 6m, 6m, 8m, 8m, and 10m and the total is 38m
If:
1m = 1.5kg
38m = ?kg
We have to multiply both sides by 38
1m × 38 = 38m
1.5kg × 38 = 57kg
So, the total weight of metal in the frame is 57kg

Well, there's 1000 milliliters in one liter.
Do 1000 - 275.
You should get 775.
The answer is 775 milliliters of juice. <span />
