Answer:
J≈36
Explanation:
There is a typo in your question and I think you meant J+3, not 3+3.
The equation to find J would be:
(J+3)×J=1330
J+3×J=1330
-3
J×J=1327
J^2=1327
J=36.42801120017
J≈36
Answer:
1.) How do solar thermal generators work?
D.) They use solar cells to covert sunlight directly into electricity
