Given information
----------------------------------------------------------
Area = 3x² + 14x + 8
Length = x + 4
----------------------------------------------------------
Formula
----------------------------------------------------------
Area = Length x Width
----------------------------------------------------------
Find Width
----------------------------------------------------------
3x² + 14x + 8 = (x + 4) x width
width = (3x² + 14x + 8) ÷ (x + 4)
width = (x+4)(3x+2) ÷ (x + 4)
width = 3x + 2
----------------------------------------------------------
Answer: The width is 3x + 2 (Answer C)
----------------------------------------------------------
-2x + 6x - 6 + 4
4x -2 Is The Simplified Expression
300miles÷15=20
Efficient:20miles/gallons of gas
Use the Pythagorean Theorem
6 feet and 14 feet are the "legs" and the ladder length is the hypotenuse.
hypotenuse^2 = 6^2 + 14^2
hypotenuse^2 = 36 + 196
hypotenuse^2 = 232
