Question
(7532 + 100 y2) + 10 (10 y2 – 110) The expression above can be written in the form
ay2 + b , where a and b are constants. What is the value of a + b ?
The correct answer is: 6632
HINT – Open the brackets
SOLUTION – Let he given expression be
F(y) = (7532 + 100 y2) + 10 (10 y2 – 110)
= 7532 + 100 y2 + 100 y2 – 1100
= 200 y2 + 6432
Comparing with the expression given in the question a y2 + b
We get, a = 200 and b = 6432
a + b = 200 + 6432
= 6632
Hence, answer is 6632

A shipping service restricts the dimensions of the boxes it will ship for a certain type of service. The restriction states that for boxes shaped like rectangular prisms, the sum of the perimeter of the base of the box and the height of the box cannot exceed 130 inches. The perimeter of the base is determined using the width and length of the box. If a box has a height of 60 inches and its length is 2.5 times the width, which inequality shows the allowable width x, in inches, of the box?
