63
Step-by-step explanation:
Yes, you can; based on the inherent assumption that the "two radicals that have negative values" are, in fact, "imaginary numbers" .
Take, for example, the commonly known "imaginary number": "i" ; which represents the "imaginary number" ; " √-1 " .
Since: "i = √-1" ;
Note that: " i² = (√-1)² = √-1 * √-1 = √(-1*-1) = √1 = 1 .

Answer:
p=43 a=78
Step-by-step explanation:
im assuming this is a triangle
perimeter is 18+12+13=43
area is 12*13=156 then divide by 2 =78
The pattern is subtracting 9
Answer: 726cm squared
Surface area is the area of all the faces added together.
If the area of one face is 11x11=121
Because it is a cube and it has six faces with the same surface area we do 121x6=726 to give us the total surface area.
