1 Tell which property the statement illustrates. Commutative Property of Addition ( CPA)

Commutative Property of Multiplication ( CPM)

Associative Property of Addition (APA)

Associative Property of Multiplication ( APM)

1. 5 x p = p x 5 CPM

2. 2 + ( 12 + r) = (2 + 12) + r

3. 4 x ( a x 10) = (4 X a) x 10

4. x + 7.5 = 7.5 + x

Good Evening,

Here are your answers,

1. 5 x p = p x 5 -  Commutative Property of Multiplication ( CPM)

2. 2 + ( 12 + r) = (2 + 12) - Associative Property of Addition (APA)

3. 4 x ( a x 10) = (4 X a) x 10 - Associative Property of Multiplication ( APM)

4. x + 7.5 = 7.5 + x - Commutative Property of Addition ( CPA)

Hope I Helped,

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
