I am not going to answer, but I can guide!
Remember the rule where you simplify the question? try doing that first! :)
I'm afraid my brain is rotting and I can't guide you further.

Answer:
C
Step-by-step explanation:
Minus two equations , we got:
9x-9y= 132-(-12)
9x-9y=144
x-y=16
Answer:
Height of the object is 68.6 cm.
Step-by-step explanation:
The height of the object can be determined by:
= 
From the given question;
object distance from pinhole = 3.6 m = 360 cm
image distance from pinhole = 4.2 cm
height of image = 0.8 cm
So that;
= 
⇒ object height = 
= 
= 68.571
object height = 68.6 cm
Thus, the height of the object is 68.6 cm.
Answer:
28.26
Step-by-step explanation:
The circumference of a circle is the distance around the edge of the circle. To find the circumference, we use the formula C = 2πr. The area of the circle is the amount inside the circle and is found using A = πr². Substitute the relevant values in each situation into the formulas to find the circumference and/or area.
Substitute C = 18.84 and solve for r. Then substitute r into the area formula.
C = 2πr
18.84 = 2πr
3 = r
A = πr² = π(3)² = 28.26
