Please help. It would mean a lot, I am very much confused...An enclosed field is made up of three sections:• One section is a 10-yard by 10-yard square.• Another section is a larger square.• A third section is rectangular with a width of 10 yards. It shares a side with the larger square.The total area of the enclosed field is 975 square yards.Part 1What is the area, in square yards, of the smallest section? (Use only the digits 0 – 9 to enter a number.)Part 2What is the area, in square yards, of the largest section? (Use only the digits 0 – 9 to enter a number.)Part 3What is the area, in square yards, of the remaining section? (Use only the digits 0 – 9 to enter a number.)

Two systems of equations are shown below:System A6x + y = 22x − 3y = −10System B−x − y = −3−x − y = −3Which of the following statements is correct about the two systems of equations? (5 points)Group of answer choicesThe value of x for System B will be 4 less than the value of x for System A because the coefficient of x in the first equation of System B is 4 less than the coefficient of x in the first equation of System A.They will have the same solution because the first equations of both the systems have the same graph.They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A.The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.
