Factor completely and then place the factors in the proper location on the grid. 36x 2 + 60x + 25
Aleonysh [2.5K]
Since 36x² + 60x + 25 is the perfect square trinomial, we use this formula a² + 2ab + b² = (a + b)². Hence, the solution is (6x + 5)²

Solve the inequality x divided by 6 is less than or equal to 3
Alja [10]
Your inequality looks like this:
\frac{x}{6}  \leq 3
To get rid of the /6, you need to multiply by 6 as the opposite operation cancels it out. So, all you need to do is multiply both sides by 6 to isolate x. 
Therefore:
x \leq 18
