Which expression should you multiply the 3 sqr root 3/ 3 sqr root 2x
by to
numerator and denominator of
rationalize the denominator?

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 -

they would have to work 32 hours.

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
