Answer:
D) 21
Step-by-step explanation:
The formula for finding the area of a triangle is A = 1/2 B x H. So, A = 1/2 (7)(6).
A = 1/2 (42)
A = 21.
So the area of the shaded region is 21 square units.

Answer:
22x + 33y + 11z
Step-by-step explanation:
11(2x + 3y + z)
11 * 2x + 11 * 3y + 11 * z = 22x + 33y + 11z
Answer:
-42+10i
Step-by-step explanation:
*start with the square roots
\sqrt{-25} \\ =5i
\sqrt{-100} \\ = 10i
*then insert values
(2+5i)(4-10i)
*Use FOIL to multiply
2x4 + 2x-10i + 5ix4 + 5ix10i
*Simplify
8-10i+20i+50i(squared)
*Add like terms
-42+10i
*( i squared = -1 )
