Which expressions are completely factored? select each correct answer. pick more then 1 18x4−12x2=6x(3x3−2x) 12x5+8x3=2x3(6x2+4) 24x6−18x5=6x5(4x−3) 20x3+12x2=4x2(5x+3) which statements are true? select each correct answer. pick more then 1 8x3−6x=2x3(4−3x3) 30x4−12x3=6x3(5x−2) 100x3+5=5x3(20x+1) 4x2+10x=2x(2x+5)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
