Area (square mirror)=side²
Therefore:
side²=256 in²
side=√(256 in²)=16 in
Rectangular mirror:
width= square mirror width=side=16 in
length=(width + 2 in)=16 in + 2 in=18 in.
Area(rectangular mirror)=length x width.
Area (rectangular mirror)=(18 in)(16 in)=288 in².
Answer: the area of a rectangular mirror is 288 in².
Answer:
4
Step-by-step explanation:
in base 4
21 = (2 * 4) + (1 * 1) = 9
Answer:
Complex and imaginary number
Step-by-step explanation:
First, let's write the number
in the form of
.

Since
can be written in the form of
, where
and
are real numbers, it is a complex number.
Also, since
, it is also an imaginary number.
is complex and imaginary.
Step-by-step explanation:
there is no diagram so I'm just going to guess this however
sin x = 6/9
sin x = 2/3
sin x = 0.67
x = sin inverse of 0.67
x = 42.1
