Answer:
7.9
4.2
9.3
17.8
Step-by-step explanation:
8. √63
the square of 8 is 64 √63 is close to 64 so we can say it's 7.9 approximately
9. √18
the square of 4 is 16, √18 is greater than 16 so we can say it's 4.2 approximately
10. √87
the square of 9 is 81, √87 is greater than 81 so we can say the value of it is approximately 9.3
11. √319
the square of 18 is 324, √319 is smaller than 324 so we can say it's 17.8
The answer is 1620.
simple
Answer:
Step-by-step explanation:
set the two equations equal to each other then solve for n
6n + 3 = 4n + 11
2n = 8
n = 4
plug n in for both equations
6(4) + 3
24 + 3 = 27
4(4) + 11
16 + 11 = 27
27 + 27 = 54
the distance is 54
