Which statement shows how the product of (x + 7)2 demonstrates the closure property of multiplication? x2 + 14x + 49 is a polynomial x2 + 14x + 49 may or may not be a polynomial x2 + 49 is a polynomial x2 + 49 may or may not be a polynomial

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
