an art class is making a mural for their school which has a triangle drawn in the middle. the length of the bottom of the triangle is x. another side is 14 more than three times the length of the bottom of the triangle. the last side is 15 more than the bottom of the triangle. write and simplify an expression for the perimeter of the triangle.

no

step-by-step explanation:

answer

x=3y-6

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.

you need to show the graph ; -;

step-by-step explanation:

hello,

elba writes the following proof for the theorem: if the diagonals of a quadrilateral bisect each other, the quadrilateral is a parallelogram:

elba's proof

1. for triangles aob and cod, angle 1 is equal to angle 2 as they are vertical angles.

2. ao = oc and bo = od because it is given that diagonals bisect each other.

3. therefore, the triangles aob and cod are congruent by sas postulate.

4. similarly, triangles aod and cob are congruent.

5. by cpctc, angle abd is equal to angle cdb and angle adb is equal to angle cbd.

6. as the are congruent, the opposite sides of quadrilateral abcd are parallel.

7. therefore, abcd is a parallelogram.

which is the missing phrase in elba's proof?

answer - opposite
