Answer:

2x+3

Step-by-step explanation:

x+x+3=2x+3

sum means to add both expression together and we can see there are 2 x's so we can add them and get 2x+3

The table shows values for functions
Studentka2010 [4]

Answer:

The study examined stochastic stability of EEG samples recorded in succession from the same healthy volunteer at unchanged state. The absence of statistical repetitions not only for EEG samples, but also for the corresponding spectral densities was proven. A method to calculate the pairwise comparison matrices of ECG samples and quasi-attractors was proposed. The diagnostic effectiveness of these calculations was demonstrated during photostimulation, when successive EEG samples chaotically changed under overall homeostatic conditions.

... It was about the need for a third science that W. Weaver spoke about in 1948 [8]. Now it is the theory of chaos-self-organization, which, according to K. Gödel's theorem, has gone beyond the bounds of deterministic and stochastic science -DSS [9][10][11][12][13][14][15][16][17][18]. ...

... that the European Association of Cardiology recommends registering the heart rate for at least 5 minutes (for example, the parameters of the cardio intervals). At the same time, it is believed that during this period a sample of 300 (or more) cardio intervals will be obtained, and this sample should be quite representative [14][15][16][17][18]. ...

... What kind of evidence-based medicine can we talk about in the study of cardiovascular system if 85% or more of the compared cardio intervals samples do not statistically coincide (they do not belong to the same general population)? Obviously, further use of stochastic methods is not advisable [14][15][16]20-23] for cardiovascular system studying, which was pointed out by W. Weaver [8]. ...

... These special properties of the TTS (complexity) are based on the lack of statistical stability of any samples of the components of the state vector of any biosystem x=x(t)=(x1, x2, …, xm)T, where xi(t) represents the parameters of the biosystem. This was first proved in the form of the Eskov-Zinchenko effect (EZE) in biomechanics [5][6][7][8][9][10], and then for other biosystems [11][12][13][14][15][16]. The EZE extends not only to samples of tremorograms (TMG), teppinggrams (TPG), electromyograms (EMG), RR intervals (RR) and other parameters of the human body, but also to their spectral densities of signals (SDS), autocorrelations A(t) and other characteristics xi(t). ...

... Elements of this matrix (see table 1) represent the Newman-Keuls test p for pairwise comparison of TMG samples. If p≥0.05, then this compared pair of TMG can be attributed to one (same) sampled population [11][12][13][14][15][16]. From table 1, it follows that the number k1=7 of such pairs is extremely small. ...

Factor the trinomial f(x) = 2x² + 5x – 12 ?
gavmur [86]

Answer:

(x + 4)(2x - 3)

Step-by-step explanation:

Given

f(x) = 2x² + 5x - 12

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × -12 = - 24 and sum = + 5

The factors are + 8 and - 3

Use these factors to split the x- term

2x² + 8x - 3x - 12 ( factor the first/second and third/fourth terms )

2x(x + 4) - 3(x + 4) ← factor out (x + 4) from each term

(x + 4)(2x - 3)

Thus

f(x) = 2x² + 5x - 12 = (x + 4)(2x - 3) ← in factored form
