Answer:
Square.
Step-by-step explanation:
given J(-4,2) || K(0,3) || L(1,-1) || M(-3,-2)
given below the visual answer.
OR
you can find the distance of coordinate to coordinate:
Distance of JK
√(-4-0)² + (2-3)²
√17
Distance of KL
√(0-1)²+(3--1)²
√17
Distance of LM
√(1--3)²+(-1--2)²
√17
Distance of MJ
√(-3--4)²+(-2-2)²
√17
All sides are similar of √17 , so its a square.
Answer:
$159.95
Step-by-step explanation:
Let price of trumphet be defined by 
price of clarinet = $139.95
Number of clarinets sold = 19
Earning through clarinets' sale = 
Total earning of store = $4578.45
Earning through trumphets' sale = 
price of one trumohet = 
price of clarinet = $159.95
Assuming the numbers are exponents expect the coefficient of 2, top expression, -12x^3y^6, multiply bottom
and= 72x^4y^8
