Perfect Square Trinomials have first and last terms that are positive perfect squares. And the middle term is twice the product of the square roots of the first and third terms.

First term:

n^2

Square root = n \checkmark

Third term:

9

Square root = 3 \checkmark

9 * 1 = 9

9 * 2 = 18

18 \neq-9

Therefore it is not a perfect square trinomial.

Solve 5x – 1 = 3x – 15. Explain each step, and include the Properties of Equality that you used.
artcher [175]

5x – 1 = 3x – 15

Subtraction Property of Equality  (Subtract 3x from both sides)

2x - 1 = -15

Addition Property of Equality   (Add 1 to both sides)

2x = - 14

Division Property of Equality   (Divide both sides by 2)

x = -7

Relative density was determined for one sample of second-growth Douglas fir 2 x 3 4s with a low percentage of juvenile wood and
Citrus2011 [14]

Answer:

0.03865

Step-by-step explanation:

Since the true density for the two types of trees are given, we would evaluate the average for both of them

Low percentage of juvenile wood density = 0.523 and 0.0543

Average density = 0.523 + 0.0543/2

Average density = 0.55015

Moderate percentage of juvenile wood density = 0.489 and 0.0450

Average density = 0.489 + 0.0450/2

Average density = 0.5115

Therefore, difference in true average density for the two woods are = 0.55015 - 0.51150

= 0.03865
