to solve the equation , we need to take "square root" of both the sides so we can isolate the variable "x".
note: when taking square root, we need both positive(+) and negative(+) value as both positive & negative value's square is same.
answer choice d is right.
so we need to take square root of both the sides to isolate the variable x and solve. thus:
now, we cannot take the square root of a negative number. hence, we cannot solve this. it is undefined.
answer choice a is right.
a square has an area given by , where s is side length.
equating the area to 79 and solving for s gives us the length of one side of the rug (remember to take square root of both sides to isolate s):
note: we disregarded the negative value of -8.89 because length cannot be negative!
hence, answer choice d is right.
