Solve for n.

-67=-4n+3(1+6n)

show work!

-67 = -4n+  (1+6n)

-67 = -4n + 3 + 18n

-70  = 14n

n = -5

Hope this helps :)

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to

pls mark as brainliest

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
