Answer:
2.97×10³
Step-by-step explanation:
3600 - 6.3×10² = 3600 -6.3×100 = 3600 -630 = 2970
= 2.97×1000
= 2.97×10³

4.) -9p + 17
5.) -15b^2 - 1b + 6c
6.) -4j
Answer: We should add the constant 81 to the expression to have a perfect square trinomial.
The perfect square trinomial that would be formed would result from (x + 9)^2.
We can use foil to prove it.
(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81
81 is the value that must go with 18x in the middle to form the perfect square trinomial.
