Please help.

(1) A rectangle has a length of 6 and a width of y + 4. Use the distributive property to write an expression to represent the area of the rectangle.

(2) A rectangle has a length of 6 and a width of y + 4. Use your area expression to find the area of the rectangle when y = 3 1/2 inches. Show your work.

(3) The area of a rectangle is 8w + 18 square feet. The length of the rectangle is 2 feet. Use factoring to write an expression to represent the width of the rectangle.

(4) The area of a rectangle is 8w + 18. Use your width expression to find the width of the rectangle when w = 1.25 feet. Show your work.

(5) The sixth grade band students are selling magazines to raise money for new instruments. As a reward for selling, the students earn points to spend on prizes. Each student gets 25 points to start with, and then they earn an additional 5 points for each magazine they sell. If m represents the number of magazines a student sells, write an expression to represent the total number of points the student has.

(1)
A = length * width
A = 6 (y+4)
A = 6y+24
(2)
A = 6(3.5)+24
A = 21+24
A = 45
(3)
A = length * width
8x+18 = 2 * width
2(4x+9) = 2* width
4x+9 = width
(4)
A = length * width
8(1.25)+18 = 1.25*l
10+18 = 1.25*l
28/1.25 = l
22.4 = l
(5)
y = 5m+25
