Express the area of the square as a monomial 9c^6d

Area of a square = side times side

A=9c^6d * 9c^6d

When multiplying exponential values of the same base (c) you add the exponents together.

A=81c^12d^2 units

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
