Answer:
E) x2 + 10x + 25
Step-by-step explanation:
A number is increased by 5, and then squared is
(x + 5)^2
When taken out of the parenthesis it is:
x2 + 10x + 25 is your answer.
Answer:
a. 16000 units
b. 11800 units
Step-by-step explanation:
A.
To get equivalent units of production for materials
Add up the units transferred out + ending work in progress
= 9000 units + 7000 units
= 16000 units
B.
To get conversion cost for November:
Units that are transferred out + (ending work in progress * % of conversion)
= 9000 + (7000 x 40%)
= 9000 + 2800
= 11800 units
The answers are therefore
1. 16000units
2. 11800 units
