6
The 6 is the constant because it is never going to change
f(x), and others that contain x will change based on the value x
Since 6 doesn’t have the c with it it will be constant

Answer:
Step-by-step explanation:
The main limitation of using the cellulose is that it is obtained from plant cell and it cannot be used in abundant amount. Although the most abundant form of carbohydrate found is cellulose but we cannot extract it from the plants for using it
A = 7n + 2
a₁ = 7*1 + 2 = 9
a₂ = 7*2 + 2 = 16
a₃ = 7*3 + 2 = 23
.
.
.
a₂₀ = 7*20 + 2 = 142
This is an Arithmetic progression, a = 9, last term = 142
Sum of the 20 terms using: n/2(a + l) where l = last term.
= 20/2(9 + 142)
= 10 * 151
= 1510
Sum of the first 20 terms = 1510
