Which expression could you find the distance between (10,4) and (-6,4) ?
a. |10| + |-4|
b. |10| = |4|
c. |-6| + |4|
d. |10| + |-6|

Option D. |10| + |-6|

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

we have

(10,4) and (-6,4)

substitute

therefore

The expression that could help to find the distance is

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
