Answer:
For the perfect square trinomial (quadratic) i.e. 
, the constant term (last term) is positive.
Step-by-step explanation:
"Perfect square trinomials" are termed as the quadratics that are the outcomes of squaring binomials.
For example:
Therefore, for the perfect square trinomial (quadratic) i.e. , the constant term (last term) is positive.
198 round to the nearest hundreds is 200
198 round to the nearest tens is 200 too
Answer:
Substitute n =1, 2, 3, 4, 5 to get the first five terms.
Step-by-step explanation:
(4). 
To find the first term, substitute n = 1.
Therefore, 
= 2
= 6
= 18
= 54
= 168
Therefore the first five terms of the sequence are: 2, 6, 18, 54, 168.
(5). 
= 4
Therefore the first five terms in the sequence are: 6, 4, 8/3, 16/9, 32/27.
Answer:
d = 7, 3
Step-by-step explanation:
First, you need to isolate the absolute value
-3|d - 5| = -6
divide both sides by -3:
|d - 5| = 2
break into 2 equations:
d - 5 = 2, d - 5 = -2
solve both equations and collect solutions:
d = 5 + 2, d = 5 - 2
d = 7, 3
