A. After the mod. One wall is “x” longer than original (horizontal in diagram) and the other is “x” shorter (vertical)
(30+x)(30-x)
b. He original area = 30 x 30 = 900 sq. ft.
The mod. Area is (30+6)(30-6) = 36x24= 764 sq. ft.
So the room was largest to begin with when it was a square
Answer:
78.5
Step-by-step explanation:
The radius of the circle is 25 so youu multiply that by 3.14
25*3.14=78.5
Answer:
The original voltage in the circuit is 
Step-by-step explanation:
We are given
Current voltage is

Let's assume original voltage as Vo
we are given
it has been reduced 3 times
so,

we can plug values

Multiply both sides by 3



So,
The original voltage in the circuit is
