A circular mirror is surrounded by a square metal frame. The radius of the mirror is 2x. The side length of the metal frame is 12x. What is the area of the metal frame?

Step-by-step explanation:

If the side length of the metal frame is 12x, the area of the frame is

(12x)^2, or 144x^2.  The radius of the mirror is irrelevant here.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

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)
