Frank raked 23 of his lawn yesterday and 16 of it the day before. How much of his lawn did Frank rake over the course of the two days?

answer

39

Step-by-step explanation:

23+16 39.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
