The number is 48.
Step-by-step explanation:
x/8+3=9
x/8=9-3
x/8=6
x=6*8
x=48
2b 2a
----------------- + -----------------
(b+a)^2 (b^2 - a^2)
2b 2a
= ----------------- + -------------------
(b+a)(b+a) (b+a)(b-a)
2b(b - a) + 2a(b + a)
= ------------------------------------
(b+a)(b+a)(b-a)
2b^2 - 2ab + 2ab + 2a^2
= ---------------------------------------
(b+a)(b+a)(b-a)
2b^2 + 2a^2
= ------------------------
(b+a)(b+a)(b-a)
2(b^2 + a^2)
= ------------------------
(b+a)^2 (b-a)
Answer:
Numerator: 2(b^2 + a^2)
Denominator: (b+a)^2 (b-a)
I know this is not an answer but, I love your handwriting!
It is soooo much neater than mine!

Hope this helps :)
The first 3 rows are proportional
because when you divide the earning by car washed they all have the same unit rate of 9.5/ to answer the second part you multiply 9.5 by 88. you'll get $836
