Then solve
7(3)-15/5 = 21-3= 18
Ответ:
5.385164807
or
5.4
Step-by-step explanation:
Use the Distance Formula:
First, do (-4 - -2) exponent 2 + (2 - -3) exponent 2.
So you get: (-2) exponent 2 + (5) exponent 2.
Then, you do -2 times -2, since there is 2 as an exponent. You also do 5 times 5.
So you get: 4 + 25
Next, you add 4 + 25 and get 29.
Finally, you find the square root of 29, which is 5.385164807, or you can round it.
( I hope that is not too confusing. I couldn't do the exponents, so I just wrote it as a word. The whole thing was done with the Distance Formula.)
