Answer:

b = 3/4

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh

3/ 40 = 1/2 b ( 1/5)

Multiply

3/40 = 1/10 b

Multiply each side by 10

10 *3/40 = 10* 1/10 b

3/4 = b

Answer:

53

Step-by-step explanation:

We know the first term and common difference so we can write the explicit formula. The formula is:

aₙ = a₁ + (n - 1)d

aₙ = 8 + (n - 1) * 3

aₙ = 3n + 5

This means that a₁₆ = 3 * 16 + 5 = 53
