Answer:
1. The square of a number is equal to 9, so it means 3 is the square root (it is the first missing number). Then multiply the two numbers 9 and 3 which is equal to 27. The number is 27.
2. Equation :
4(n)=20
4n/4=20/4
n=5
20(5)=100
The number is 5
3. The equation will be 2(n + 3)=98
2(n + 3)=98
2n+6=98
2n=98-6
2n=92
by dividing both sides to 2
n=46
Let's check:
2(46+3)=98
2(49)=98
98=98
