Write the expanded form of the expression.
y(0.75 + 7)
+

y(0.75+7) = 0.75y + 7y

Step-by-step explanation:

if you open the bracket by multiplying y with the sum of the numbers you will have 7.75y

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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)
