120 + 5d = 445 <==
** parts + labor = 445
p = 120
labor = 5 hrs * d...where d is cost per hr
That would be called the quotient.
Using: A^2+b^2=c^2
A&b= (√10)^2=10
10+10=c^2
20=c^2
(take the square root of 20)
c=2√5
Your answer is D
Difference means subtraction. So you take $58.20-$53.48 and you get $4.72.
A = 4b
b = 7
a = 28
7 * 4 = 28
