Expanding the left side gives
which gives two solutions,
and
. But if
, then
, but this number isn't real, so
is an extraneous solution. Meanwhile if
, you get
, so this solution is correct.
"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.
Answer:
98 square centimeters
Step-by-step explanation:
first find the area of the non shaded area
8x4=32
next find the area of the rectangle around it
13x10=130
and last you need to subtract the non shaded area from the rectangle around it to find the area of the shaded area
130-32=98
96 divided by 3 is 32
Therefor, it is divisible by 3
