Use mental math to solve the equation z/-12 = -5

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

Consider the following equation -167 + 37 = 49 - 21p select the equation that has the same solution as the given equation. o a. p - 5 + ip = 7 - p ob. +55 + 12p = 5p + 16 c. 2 + 1.25p = -3.75p + 10 d. -14 + 6p = -9 - 6p reset next

Can someone check if i did this correct. it’s number 4 if you’re wondering.
