What is the solution set for the open sentence with the given replacement set? 17 – x = 9, {5, 6, 7, 8} a. 5 b. 6 c. 7 d. 8

Correct option is:

d. 8

Step-by-step explanation:

We have to find the solution of the equation:

17-x = 9

Now, we start solving it

Taking the term of x on one side and constant terms on the other, we get

x = 17-9

i.e. x = 8

Hence, the solution set of 17-x = 9 is:

d. 8

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
