X^2 - 18x - 144 = 0
Factorise:
We choose 2 numbers that add to -18, and multiply to 144, these numbers are +6 and -24, we put it into the brackets:
<span>(x + 6)(x - 24) <- x = the interted sign of the numbers inside the brackets
E.g. +6 turns into -6 and -24 turns into +24
x must = -6 or = +24

part 1) : the inequality showing pets need to make all the ordered cupcakes is d≤13 option d
part 2) The graph showing the solution for d is : option B
What is number line ?
Number line is virtual representation of numbers along with coordinates axis with number equally spaced with equal number of interval.
pat need at least 13 days to make all the order to make cupcakes it means minimum number of days <em>d</em> he needed will be 13 and at most no limit is there as no end condition is given therefore the inequality will be and it can be represented on number line in potion B of part 2nd of question as the line is starting from point (13,0) including 13 also and extending till infinity.
Therefore, option d and option B of the given questions are the answers
