First get them all on one side
add 7x+60 to both sides
0=x^2+17x+60
now factor
what 2 numbers mutltiply to get 60 and add to get 17?
5 and 12
0=(x+5)(x+12)
set each to zero
0=x+5
-5=x
0=x+12
-12=x
the factored form is (x+5)(x+12)=0
the solutions are x=-12 and -5

Answer: 13.2 grams .
Step-by-step explanation:
We are given that ,
In nuclear fusion, about 0.60% of the mass of the fusing substances is converted to energy.
When 22 kilograms of substance undergoes fusion , then the mass of the fusing substances is converted to energy. = 0.06% of (22 kilograms)
Convert % into decimal by dividing it by 100 and replace 'of ' by multiplication operator (x) , we get
Mass of the fusing substances is converted to energy. =
Since 1 kilogram = 1000 grams.
Therefore , Mass of the fusing substances is converted to energy. =
Hence, 13.2 grams of mass is converted into energy when 22 kilograms of substance undergoes fusion.
