Write and solve an equation to find the value of x if the polygons have the same perimeter (I should see an equation and the value of x in the answer space).

Based on your question where QRS is equals to TUV, and QS = 3v+2 and TV = 7v-6 to find the length of QS and TV first you must consider that the two are congruent and the QS = TV also which means base in my calculation the V is equals to 2 and by substituting the value of both is 8.
