Mr. grant needs 30 pieces of felt. he can buy them in packs of 10 or as single pieces. what are the different way mr. grant can buy the felt

5 packs of 6 felts

              2 packs of 15 felts

Step-by-step explanation:

6 + 6 + 6 + 6 + 6 = 30

15 + 15 = 30

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,

mrb

(x) - (y) = (1 + 4i)
