x − 1 ≤ 6

(a)x ≤ 5;

(b)x ≤ 7;

(c)x ≥ 7;

(d)x ≤ 7;

(D)x ≤ 7

Step-by-step explanation:

x − 1 ≤ 6

Add 1 to each side

x − 1+1 ≤ 6+1

x  ≤ 7

there is no grid

step-by-step explanation:

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
