The sum is the total of the given values being added.
Given the expressions above, to add them, you just have to add the numbers with the same terms. 13x2 and 8x2 have the same terms which is x2, therefore, you can add both and the result is 21x^2 then just copy 5x so the sum would be 21x2 + 5x. Hope this answer helps.
If you divide the first equation by 2 and the second by 3, you get

These equations differ only in their y-intercept, so describe parallel lines. The appropriate choice is ...
... H The lines are parallel.
Answer:
Step-by-step explanation:
21+10=31-2=29
Answer:
2/3 or 0.66 repeated
Step-by-step explanation:
Since 2022 is only divisible by 1,2,4, and 5, the probability of getting a number that is a divisor of 2020 is 4/6, simplified to 2/3 or %0.66.
Answer:
The third piece must be 14.4 inches
Step-by-step explanation:
We use the triangle inequality theorem to get the third side
using the theorem, it must be that the sum of the two will be greater than the length of the third side
Hence we have it that;
a + b > c
6.5 + 8.1 > c
14.6 > c
So what this mean is that the third length is less than 14.6
the reasonable answer out of the options is thus 14.4 inches
reason for this is that the last two options will also not follow the inequality theorem
