Answer:

(2x-1)(7xy+2)

Step-by-step explanation:

14x^{2} y+4x-7xy-2.

Making pair of two   we have :

(14x^{2} +4x) -( 7xy+2)

Taking common factor of both pairs we have:

2x(7xy+2)- 1(7xy+2)

Taking 7xy+2 as the common term we have:

(2x-1)( 7xy+2)

How do you find the area of a triangle ?
katovenus [111]

Answer:

to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.

Step-by-step explanation:

For example..

If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

You roll a pair of fair dice until you roll “doubles” (i.e., both dice are the same). what is the expected number, e[n], of roll
bonufazy [111]

We need to define our outcomes and events.

 

Finding the probability<span> of each event occurring separately, and then multiplying the probabilities is the step to <span>finding  the probability</span> of two independent events that occur in sequence.

</span>

<span>
To solve this problem, we take note of this:</span>

 

The roll of the two dice are denoted by the pair

(I, j) ∈ S={ (1, 1),(1, 2),..., (6,6) }

Each pair is an outcome. There are 36 pairs and each has probability 1/36. The event “doubles” is { (1, 1),(2, 2)(6, 6) } has probability p= 6/36 = 1/6. If we define ”doubles” as a successful roll, the number of rolls N until we observe doubles is a geometric (p) random variable and has expected value E[N] = 1/p = 6.

Need help with the question in the picture learned awhile ago and forget!
xxTIMURxx [149]

Answer:

-i

Step-by-step explanation:

i^15

Divide the exponent by 4

15/4 = 3 r 3

Take the remainder and use as the exponent

i^3

 We know that i^2 = -1  

i^3 = i^2 *i

i^3 = -1*i

-i
