[1/1 Formula]
Work: Calculate the value of equation -1/12×(6.5)^2×56.495-1/20×(6.5)^2×110.826 .
Question type: Mathematical calculation
Solution:
-1/12×(6.5)^2×56.495-1/20×(6.5)^2×110.826
=-1/12×6.5^2×56.495-1/20×(6.5)^2×110.826
=-1/12×6.5^2×56.495-1/20×6.5^2×110.826
=-1/12×42.25×56.495-1/20×6.5^2×110.826
=-1/12×42.25×56.495-1/20×42.25×110.826
=-0.083333×42.25×56.495-1/20×42.25×110.826
=(-3.520819)×56.495-1/20×42.25×110.826
=(-198.908669)-1/20×42.25×110.826
=-198.908669-0.05×42.25×110.826
=-198.908669-2.1125×110.826
=-198.908669-234.119925
=-433.028594
Answer:-1/12×(6.5)^2×56.495-1/20×(6.5)^2×110.826=-433.028594
