Answer:

- 20 + 8i

Step-by-step explanation:

Noting that i²  = - 1

Given

= ( 6i + 9 + 4i - 5 ) × 2i

= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i

= 20i² + 8i

= 20(- 1) + 8i

= - 20 + 8i

Your math teacher gives you an extra credit problem to figure out her age. Half of her age three years
MatroZZZ [7]

Answer:

Teacher is 27 years old

Step-by-step explanation:

(1/2)(t - 3) = (1/3)(t + 9)

multiply by 6 to clear the fraction

3(t - 3) = 2(t + 9)

Distribute

3t - 9 = 2t + 18

Subtract 2t from both sides

t - 9 = 18

Add 9 to both sides

t = 27

Teacher is 27 years old
