Answer for lots of points x + 5 > or equal to 2x + 1 and -4x < -8 show work for brainliest

4 >=x

x > 2

Step-by-step explanation:

x+5 >= 2x+1

subtract x from each side

x+5 -x>= 2x+1 -x

5>= x+1

subtract 1 from each side

5-1 >=x+1-1

4 >=x

-4x < -8

divide by -4  ( remember when multiplying or dividing by a negative  flip the inequality)

-4x/-4 > -8/-4

x > 2

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
