Answer:
-1 x 
Hope this helps
Step-by-step explanation:
V = lwh
2x³ + 17x² + 46x + 40 = l(x + 4)(x + 2)
2x³ + 12x² + 16x + 5x² + 30x + 40 = l(x + 4)(x + 2)
2x(x²) + 2x(6x) + 2x(8) + 5(x²) + 5(6x) + 5(8) = l(x + 4)(x + 2)
2x(x² + 6x + 8) + 5(x² + 6x + 8) = l(x + 4)(x + 2)
(2x + 5)(x² + 6x + 8) = l(x + 2)(x + 4)
(2x + 5)(x² + 2x + 4x + 8) = l(x + 4)(x + 2)
(2x + 5)(x(x) + x(2) + 4(x) + 4(2)) = l(x + 4)(x + 2)
(2x + 5)(x(x + 2) + 4(x + 2)) = l(x + 4)(x + 2)
(2x + 5)(x + 4)(x + 2) = l(x + 4)(x + 2)
(x + 4)(x + 2) (x + 4)(x + 2)
2x + 5 = l
Is the question asking f(g(x))? If so the answer is 4x+20
30 is 42% of 70 and you divide 30 by 70
Answer:
$352.80
Step-by-step explanation:
We have been given a family sell back 420 kWh for $0.07 per kWh each month.
First of all, we will find monthly income of family from solar panels by multiplying 420 by $0.07.



To find the money earned by the family is one year, we will multiply monthly income by 12 as 1 year equals to 12 months.


Therefore, the family could make $352.80 in a year from solar panels.
