Answer:
A = 140 in²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
here b = 20 and h = 14 , then
A = × 20 × 14 = 10 × 14 = 140 in²
Answer:
16
Step-by-step explanation:
(10-6)^2

The correct answer is: -18 .
________________________________________
9i * 2i = 18 i² .
________________________________________
" i " is an imaginary number equal to "√(-1) " .
" i² " = [√(-1)] ² = √(-1) * √(-1) = -1 .
________________________________________
18 * i² = 18 * -1 = -18 .
