2. ana is given the image below and asked to write an algebraic expression to represent the volume of
the shape
she writes a? - b= (a - b)(a
+ ab - b). is ana correct?
a. ana is correct
b. ana is incorrect. the expression should be a
- b) = (a - b)(a? - ab - b? )
c. ana is incorrect. the expression should be a
- b3 = (a - b)(a
+ ab + b)
d. ana is incorrect. the expression should be a
- b3 = (a + b)(a
+ ab + b)

step-by-step explanation:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
