Astudent's work to distribute and simplify a radical is shown below. select the statement which best applies to the sample mathematical work. given (-5√20+√3)*(2+√3), i first distribute to get the expression -10√20-5√60+2√3+√9, which i can simplify to -40√5-20√15+2√3+3 for an answer. a. the student did not properly distribute the radicals b. the student overlooked combining one or more of the radical terms c. the student did not properly simplify all radicals d. the work shown above is correct

Step-by-step explanation:

Given that a student's work to distribute and simplify a radical is shown below.

Given

(-5√20+√3)*(2+√3)

The next step of distribution is

-5√60+2√3+√9 is done correctly.

Next step is

-40√5-20√15+2√3+3

I term = -10√20=-20√5

Correct answer is

Hence c) the student did not properly simplify all radicals

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
