X=12 because 12 times 12 equals 144 or 12 to the power of two equals 144
(6 + 3) + 21 = 6 + (3 + 21)
It's an ASSOCIATIVE PROPERTY
(a + b) + c = a + (b + c)
Answer:
C
Explanation:
B=Base Area
In a cylinder, the base area is a circle.
Area Circle=pi r^2
Replace base area with area of circle:
V=pi r^2 H
Answer:

Step-by-step explanation:
Since, By the given diagram,
The side of the inner square = Distance between the points (0,b) and (a-b,0)


Thus the area of the inner square = (side)²


Now, the side of the outer square = Distance between the points (0,0) and (a,0),


Thus, the area of the outer square = (side)²

Hence, the ratio of the area of the inner square to the area of the outer square

Answer:
Step-by-step explanation:
<u>Simplify</u>
- 4^10 divided by 4^10 . 7^0
- 4^10/(4^10*7^0) =
- 4^10/4^10 =
- 1
