Answer:
square root of 19
Step-by-step explanation:
10^2 - 9^2 = 19
4.4 ft
10^2=9^2+b^2
100=81+b^2
Subtract 81 from both sides
19=b^2
Take the square root of both sides
√19=b or 4.4=b
96,539
41,539 + 55,000 = 96,539
60 + 12 = 72
5x + x = 72
=> 6x = 72
=> x = 72 ÷ 6
=> x =12
∴ 5×12+12=72
=> 60 + 12 = 72
2.16 = 2 16/100 = 2 4/25
