Step-by-step explanation:
<u>What is a square number</u>?
A square number is a product of a number times itself
So, the 12th square number would be 12 * 12, or 12²
The 9th square number would be 9 * 9, or 9²
The equation would be 12² + 9²
So:
12² + 9²
= 144 + 81
= 225
So, the answer is 225
Answer:
Step-by-step explanation:
The area of a trapezoid is the average of the parallel bases times the height.
A=h(a+b)/2 and since we have two identical trapezoids the total are will be
A=h(a+b) in this case
A=15(32+25)=855mm^2
Answer: 0
Explanation:
0 to the 5th power means 0 five times so
0 x 0 x 0 x 0 x 0
=0
5 km = 5000 meters
66 minutes = 3960 seconds
Meters per second = 5000/3960 = 1.26
The answer is A.1.26
