Answer:
6x^2 -29 +35.
Step-by-step explanation:
use the FOIL method(First, Outer,Inner, and Last.)
2x x 3x=6x^2.
2x x -7=-14x.
-5 x 3x =-15x.
-5 x -7=35.
= 6x^2 -14x -15x+35
6x^2 -29x +35.
Answer:
40.5g of salt is left after evaporating all the water.
Step-by-step explanation:
Here, 9% of 450g means that out of 450 gram of solution, 9% is the salt.
So, we need to calculate 9% of 450
i.e. 9% * 450 = 0.09 * 450 = 40.5g
Hence, 40.5 grams of salt is in 450 grams of solution.
i.e. 40.5g of salt is obtained after evaporating all the water from the solution.
