Plug x = 0 to check
You cant take log of negative number or 0 so x = 0 is not a solution.
Answer:
a²+b²=c² so you take 15² =225. then you take 8²=64 then you add 225+64=289. Then you find the √289 That equals 17
C=17
1 / 128 = (2/3) / x....1 cup to 128 grams = 2/3 cups to x grams
cross multiply
(1)(x) = (128)(2/3)
x = 256/3
x = 85.3
he went over...
85.3 - 32 = 53.3....he went over by 53.3 (or 53 1/3) grams
The answer is 186 sq hope i am right
