Solve nx + 4 for x

question 5 options:

x = h + 4

x = h/n

x = hn

x = (h - 4)/n

From what I can see, this problem is unsolvable due to the fact that your missing a variable in the equation. If the equation was for instance h=nx+4 the answer would be (h-4)/n=x or something like that. Going by the possible answers, I'm guessing x=(h-4)/n is the correct one

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
