Answer:

$\sqrt{118}$ or 10.8627805

Step-by-step explanation:

Start by taking the difference of each value of both points

Find the difference in x values

78-2 = 76

Find the difference in y values

46-4 = 42

Add the two differences

76+42=118

Take the square root of this value

$\sqrt{118}$

Round 9118 to the nearest ten

gavmur [86]

(8)=ones place

(1)0=tens place

(1)00=hundreds place

(9)000=thousands place

The "1" beside the 8, is the tenths spot so you would round that part of the number.

Therefore the answer would be:

9120
