Simply divide 40 by 63 to revile that 40/63 is 63.5%. It's grade equivalent is approximately a "D".
It is equivalent to d - 28.

The expression d squared plus 16d plus 48 can be factored as (d + 4)(d + 12).

7d - 12 + 2d + 3 = 18Group the like terms for d on the left side. Move the integers to the right side remembering to reverse their signs (positive/negative)7d + 2d = 18 + 12 - 3Which becomes:9d = 27Divide each side by 9:d = 3
