Step-by-step explanation:

first you plug in the numbers where they belong...

(-4-1)²+2(1)- 7(-4)

now you do the Order of Operations

P  anything in ()

E exponents (²)

M multiplication

D division

A addition

S  subtraction

first do (-4-1)²

-5²= -5* -5= 25

now we have... 25+2(1) - 7(-4)

now do 2*1= 2      also do   7 * (-4)= -28

now we have 25+2-(-28)

because there is that -(-28) just make it a +28

now do 25+2+28

27+28

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
