Square for the following equation? -2x2 + 160 = 40x Submit Answer

Put the -2x under the 40x
2+160 =-2x
162=42x
X=3.8

The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second.
How many ergs the sun produce in 3.25 ⋅ 10^3 seconds

3.9 ⋅ 10^33 x 3.25 ⋅ 10^3
= (3.9 x 3.25)(10^33 x 10^3)
= 12.675 x 10^36
= 1.2675 x 10^37

answer
1.2675 x 10^37 ergs of radiant energy the sun produce in 3.25 ⋅ 10^3 seconds
