Answer:

I Disagree cuz when you divide you are supposed to do it by flipping the numerator and denominator at the right and then multiply. So the correct answer should've been 4 and 1/2.

Now about that Brainly you promised...

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: $d \approx 13.5$
