Solve the following;
25 ≥ 2a -9
please help!!!

a ≤ 17

Step-by-step explanation:

25 ≥ 2a -9

To solve the equation above, we are going to follow the step below;

First, we will add 9 to both-side of the inequality

25 ≥ 2a -9

25 +9 ≥ 2a -9 + 9

34  ≥ 2a

To get the value of a, we will divide both-side of the inequality by 2

34/2 ≥ 2a/2

(On the right-hand side of the inequality, the 2 at the numerator will cancel-out the 2 at the denominator while on the left-hand side of the equation 34 will be divided by 2)

34/2 ≥ a

17 ≥ a

which implies: a ≤ 17

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
