Jake says that there should be a decimal point in the quotient 142.45 divide 1,925 after the 2. Part A

Which equation shows the best estimate for the quotient?

A: 150 divide 10 = 15

B: 140 divide 10 = 14

C: 150 divide 5 = 30

D: 140 divide 7 = 20

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

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
