Using the drawing tools to form the correct answer on the provided number line. consider the functions below f(x)=|3x| +3

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

30 feet

step-by-step explanation:

c

step-by-step explanation:

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 -
