Okay its topic is '' Multiplications in Algebraic expressions''
It is done with distributive property of multiplication to addition and subtraction.
(4+5i). (4-5i)
It's like (x+y)(x-y) rule.
The answer must be
But I don't recommend you to memorise, you should solve it yourself! :)
Anyways, let's try solving it.
By the way, you must learn distributive property before solving once.
Hope it helps!

Answer:
20%
Step-by-step explanation:
200 mocha flavored cupcakes of the 500 cupcakes were sold. (200/500).

Answer:
f(3) = 0
Step-by-step explanation:
Plug in 3 for x:
f(x) = x - 3
f(3) = (3) - 3
Simplify. Combine like terms:
f(3) = (3) - 3
f(3) = 3 - 3 = 0
f(3) = 0
f(3) = 0 is your answer.
