A contractor is building a house with a large hexagonal palladium window above the front door. He needs to calculate the area of the window.
The area of the rectangular portion of the window can be represented by the function A(x) = 2x2 + 10x. The area of the trapezoidal
portion can be represented by the function A(t) = 6/(X + 15) + (2x + 10), Formulate a function Aſw) that can be used to represent
the area of the entire window.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
