What’s the correct answer for this?

Distance between two points (x1, y1) and (x2, y2):

D = sqrt((x1 - x2)^2 + (y1 - y2)^2)

Then, distance between two points (5, 9) and (-7, -7):

D = sqrt((5 + 7)^2 + (9 + 7)^2) = sqrt(144 + 256) = sqrt(400) = 20

=> Option A is correct

Hope this helps!

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
