Answer:
8x^2 + 18x - 35.
Step-by-step explanation:
Area = (4x - 5)(2x + 7)
= 8x^2 + 28x - 10x - 35
= 8x^2 + 18x - 35.
hour hand = 7.5 x 2 for the diameter. C = 2(pi)(15) = approx. 94 centimeters. Minute hand = 9.5 x 2 = 19, C = 2(pi)(19) = approx. 119 centimeters
-10x+18=10x+4
20x=14
x=14/20=7/10=0.7
