Answer:
length times width for area so its 5x6=30
4x____ = 6 so that both sides equal 24
-24a²- 6a +9 = - 3(8a² +6a - 9)
8a² +6a - 9 =0
x=(-b +/-√(b² - 4ac))/2a
x = (-6 +/-√(36+4*8*9) /(2*8) = (-6 +/-√(324) /16 = (-6 +/-18)/16
x1 = (-6 +18)/16 = 0.75
x2 = (-6 -18)/16 = - 1.5
-24a²- 6a +9 = - 3(8a² +6a - 9) = -3(a - 0.75)(a + 1.5)
Answer:
64 numbers
Step-by-step explanation:
Answer:
Total number of coffee pot = 16 pots
Step-by-step explanation:
Given:
Time taken for drying all coffee pot = 10 minutes
Total time taken for cleaning and drying coffee pot = 82 minutes
Time taken for clean a coffer pot = 4 ½ minutes = 4.5 minutes
Find:
Total number of coffee pot
Computation:
Total time taken for cleaning = Total time taken for cleaning and drying coffee pot - Time taken for drying all coffee pot
Total time taken for cleaning = 82 - 10
Total time taken for cleaning = 72 minutes
Total number of coffee pot = Total time taken for cleaning / Time taken for clean a coffer pot
Total number of coffee pot = 72 / 4.5
Total number of coffee pot = 16 pots
