Mariah is required to load loaves of bread on trays to prepare for shipping. her goal for 8 hours of work is to load 500 trays of bread. each tray can hold 12 loaves of bread. if mariah has loaded 300 trays of bread in her first 4 hours, how many more loaves of bread will she need to load on trays per hour to reach her goal in time? *

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

we are given polynomial 2x^2 +4x +7.

we need to determine the number of roots of the given polynomial using the fundamental theorem of algebra.

a) for the given polynomial 2x^2+4x+7, we have degree =2.

b) let us find the roots of the given polynomial.

2x^2+4x+7= 0
