Answer:
I think it is 9
Step-by-step explanation:
as for number one I did 5×7=35 overall and 15×21= 315
then I did 315÷35=9 which is the scale factor.
hope this is correct and help u understand:)
Suppose :
2^x = t ..**&**.. 3^y = u
_____________________________
t + u = 9 × 3 3t + 3u = 27
=====》
2t - 3u = 8 2t - 3u = 8
+ __________
5t = 35
5 × t = 5 × 7
t = 7
&
u = 2
________________________________
Thus :
2^x = 7 ===》 x = Log _ 2 { 7 }
3^y = 2 ===》 y = Log _ 3 { 2 }
