Astudent’s work to simplify and combine radicals is shown below. select the statement which best applies to the sample mathematical work.

given 2003-04-03-00-00_files/i027.jpg, i observe that 2003-04-03-00-00_files/i0270001.jpg and 2003-04-03-00-00_files/i0270002.jpg , and that 25 and 4 are perfect squares, so i simplify the expression to 2003-04-03-00-00_files/i0270003.jpg . i can then combine these terms to get 2003-04-03-00-00_files/i0270004.jpg , which is my answer.

The equation respenting the left table is

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.
