Which expression shows the result of applying the distributive property to −2(13x−15)? 23x−25

−23x−25

−23x+25

23x+25

none of these answers are right.

Step-by-step explanation:

The correct answer would be

-26x+30

because you would do -2 times 13x and 2 times -15 to get -26x and 30, respectively. You would get the answer -26x + 30.

Hope this helps :)

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
