Rudolph had Algebra II test scores of 87 and 83 on his first two tests. He then forgot to do his homework and earned a 40 on his third test. What would he need to score on the fourth test in
order to earn an average of at least 75 on his test?

PLEASE SHOW WORK !

P = 16 inches

A = 15 square inches

Step-by-step explanation:

The rectangle has a length from (2,3) to (2,8) which is a vertical distance of 5 units since 8-3=5. The rectangle has a width of (2,8) to (5,8) which is a horizontal distance of 3 units since 5-2 =3

This means the rectangle is 5 units by 3 units.

The perimeter of a rectangle is equal to P = 2b+2h where b=base and h=height. Here the base is 5 units and the height is 3 units.

P = 2*5 + 2*3

P = 10 + 6

P = 16 inches

The area of a rectangle is A = b*h. Substitute b=5 and h=3.

A= 5*3

A = 15 square inches
