Answer:
Step-by-step explanation:
(x+3)² -5 =0 , use the formula (a+b) ² = a²+b²+2ab
x²+9 +6x -5 =0 , combine like terms
x²+6x +4 =0, use the quadratic formula x = (-b±√b²-4ac)/2a
x= (-6 ±√6²-4*1*4)/2*1
x= (-6 ± √36-16) /2
x= (-6±√20)/2
x=(-6 +2√5)/2 and x=( -6-2√5) /2, factor 2 in the numerator and simplify
x= -3 +√5 and x= -3 -√5

Answer: 4.5p + 40 = 112
Step-by-step explanation:
Let p represent the number of pairs of shoes that Roger must sell in a day to meet his daily earnings goal.
Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. This means that if he sells p shoes in a day, his total earnings for that day is expressed as
4.5p + 40
Since his daily earnings goal is $112, then the equation to determine how many pairs of shoes he must sell to meet his daily earnings goal is
4.5p + 40 = 112
