The expression d squared plus 16d plus 48 can be factored as (d + 4)(d + 12).
What is 2 plus d
Well, in my middle school thy don't have the letter system. They just use percentages so I thin that the d+ would be I think a fifty I might be wrong but I probably am.
A B plus C plus D plus E plusorA B C D E plus plus plus plusor variations.
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
8d of course
a(c+d)+b(c+d)=(a+b)(c+d)
The reaction A plus B forms products C and D.
a + d
the answer is a
They are terms of an algebraic expression which can be simplified to: 2s+2d
