Answer:
8 and 9
Step-by-step explanation:
<u>Since 77 is between 64= 8² and 81= 9²</u>
- √64 < √77 < √81
- 8 < √77 < 9
it means to place the little dot (or decimal) in the correct position next the number. Makes sense?
consider first number is = x
formula,
(n / 2)(first number + last number) = sum,
7/2(x+x+6)= 945
2x+6= 945×2/7
2x+6 = 270
2x= 270-6
x=264/2= 132
Answer the smallest number is 132.
130 would be the correct answer
