Alinara [238K]

Answer:

\huge ( {2d}^{2}  + 5)(d + 3)(d - 3)

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • factoring
  • PEMDAS
<h3>given:</h3>
  • 2d^4-13d^2-45
<h3>let's solve:</h3>

2d^4-13d^2-45

2 {d}^{4}  + 5 {d}^{2}  - 18 {d}^{2}  - 45 \\  {d}^{2} ( {2d}^{2}  + 5) - 9( {2d}^{2}  + 5) \\ ( {2d}^{2}  + 5)( {d}^{2}  - 9 )\\ ( {2d}^{2}  + 5)(d + 3)(d - 3)

Suppose a triangle has two sides of length 2 and 3 and that angle between these two sides is 60 degrees. What is the length of t
Arturiano [62]

Answer:

Apply cosine rule:

c²=b²+a²-2ba cosC

C= pi/3 = 180/3 = 60 degrees

cosine 60 deg = 0.5

c²=2²+3²-[2×2×3×0.5]

c²=7

c=√7

c=2.645 ;length of third side of angle

Using the ruler postulate, find the distance between –9 and 2.
gulaghasi [49]

Answer:

11 units

Step-by-step explanation:

According to ruler postulate, if there are two points A with coordinate a

and point B with coordinate b, \

then distance ab is given by subtracting coordinate in any order i.e it can be (a-b) or (b-a) and then take the absolute value value of it.

mathematically it can be represented as

AB = |a-b| or |b-a|

_________________________________________

in the given problem points are -9 and 2

thus distance

distance between –9 and 2  = |-9 -2| = |-11|  = 11

absolute value of -11 is 11

alternatively, distance can be calculated as

distance between –9 and 2  = |2 -(-9) | = |2 + 9 | = |-11|  = 11
