Hich is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y 2x3y4 xy3? both the sum and difference have a degree of 6. both the sum and difference have a degree of 7. the sum has a degree of 6, but the difference has a degree of 7. the sum has a degree of 7, but the difference has a degree of 6.

The correct option is 3.

Step-by-step explanation:

The degree of a polynomial is the sum of the exponents of all the variables that appear in it.

The given expressions are

The sum of these expression is

The degree of sum is 6.

The difference of these expression is

The degree of difference is 7.

Since the sum has a degree of 6, but the difference has a degree of 7, therefore the correct option is 3.

which expression represents the approximate length of bc?

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
