The cookie recipe calls for 1/2 cup of flour to make 8 servings. how many cups of flour are needed to make 20 servings of cookies? explain.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
