Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point E (9,0)

Point F (0, -10)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(0-9)^2+(-10-0)^2}$
Subtract: $d = \sqrt{(-9)^2+(-10)^2}$
Exponents: $d = \sqrt{81+100}$
Add: $d = \sqrt{181}$
Evaluate: $d = 13.4536$
Round: $d \approx 13.5$

Antonio gave 21 tomatoes to his neighbor and 15 to his brother .he had 72 tomatoes before giving some away .how many tomatoes do

Butoxors [25]

He has 36 tomatoes left. Since he had 72 tomatoes in the beginning but gave away 21 to his neighbor and 15 to his brother, you have to subtract those two values from 72. The equation would be 72-21-15 which results in 36. Therefore, Antonio has 36 tomatoes left.
