Determine whether the expressions are equivalent.

8x+4y is ___ to 4(2x+1)

Equivalent. 8x+4y=8(x+4y)

Equivalent. 8x+4y=4(2x+1)

Not equivalent. 8x+4y=6x(4y+2x)

Not equivalent. 8x+4y=4(2x+y)

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

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
