A regular model refrigerator costs $514 and has an estimated annual operating cost of $84. An energy-saving model costs $610 and has an estimated annual operating cost of $60. How many years will it take for the total cost of buying and operating each model be the same? PLS HELP (I WILL GIVE BRAINLIEST)

4 years

Step-by-step explanation:

514 + 84x = 610 + 60x

514 + 84x - 60x = 610

84x - 60x = 610 - 514

24x = 610 - 514

24x = 96

x = 96 ÷ 24

x = 4

So, the answer is 4 years.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

answer: 1+1

step-by-step explanation: 1+1 is at least 2
