there are 60 minutes per hour
99/60 = 1.65 km per minute
1.65 x 2 = 3.3 km in 2 minutes
Step-by-step explanation:
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42
Answer:
x=23
