Arrange each trinomial in descending order and then find their sum. 5 + x2 + 2x x + x2 – 1​

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
