Answer: b.) 40
Given that:
f(x) = 5 × 2ˣ
To find f(3), simplify insert [x = 3] in the given equation:
f(3) = 5 × 2³
f(3) = 5 × 2 × 2 × 2
f(3) = 40
11.) All you've got to do is subtract thirty-eight(38) from eighty-one(81). This will result in 43.
81-38=43
12.) You've got to subtract eighty-seven(87) from ninety(90) which will give you the answer 3.
87-90=3
The factor of the 
will be 3(3x-5)(2x+1).
<h3>What will be the factor of
?</h3>
Given quadratic equation is
By taking 3 common from whole of the equation it becomes.
now by factorization equation will be.
3[(2x(3x-5)+1(3x-5)]
Taking (3x-5) common from whole equation it will become
3(3x-5)(2x+1).
Hence the factor of the will be 3(3x-5)(2x+1).
To know more about factorization follow.

Answer:
c
Step-by-step explanation:
The answer is 18.
Work:
[i]The range is the gap between the smallest value and the largest value. [/i]
The smallest is 68.
The largest is 86.
The gap between them is 86-68=18.
