Jason is trying to prove that this quadrilateral is a rhombus. using the slope formula, he finds that opposite sides of the polygon are parallel. since all of the sides appear to be congruent, jason concludes that abcd is a rhombus. is jason's reasoning correct? why or why not?

incorrect; Jason must also prove that all sides are congruent by using the distance formula.

Step-by-step:

By definition, a rhombus has two pair of parallel sides and all sides are congruent. Jason must use the distance formula in a formal algebraic proof to prove that all sides are congruent. Just looking at the graph is not sufficient proof.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

ok
