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? a) correct; jason can tell by looking at the graph that all sides are congruent. b) correct; a rhombus has two pairs of parallel sides which may or may not be congruent. c) incorrect; jason must also prove that all sides are congruent by using the distance formula. d) incorrect; a rhombus does not have two pairs of parallel sides. jason must prove that all sides are congruent.

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

Step-by-step explanation:

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
