Type the correct answer in each box. Write your answers in decimal form, rounded to the nearest tenth, if necessary. Type the solution with the smaller value in the first blank. (Hint: to complete your calculations, you may need to use mental math.) Select and use the most direct method to solve 2x(x + 1.5) = -1. Part B Question Type the correct answer in the box. Solve this equation using the most direct method: 3x(x + 6) = -10 Enter your solution in the exact, most simplified form. If there are two solutions, write the answer using the ± symbol. Part C Describe and justify the methods you used to solve the quadratic equations in parts A and B.

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.

i hope this is what you were looking for.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
