I will assume 'xx' as one variable, in other words, it isn't equal to x²:
⇒ its just 'xx'
For question 32, let's solve:
[tex]\frac{xx}{9}=\frac{2}{3} \\3xx=9*2\\3xx = 18\\xx=6[/tex] --> choice (c)
For question 33, let's solve:
[tex]\frac{3}{xx} =\frac{5}{xx-2}\\3(xx-2)=5*xx\\3xx-6=5xx\\5xx-3xx=-6\\2xx=-6\\xx=-3[/tex]--> choice (b)
Answers:
- For question 32: (c)
- For question 33: (b)
Hope that helps!
