8.5x10^12
decimal moves left 12 spaces so that the 85 part is greater than 1 but less than 10
Factor them
2a^2-ab-3b^2=(2a-3b)(a+b)
2a^2-5ab+3b^2=(2a+3b)(a+b)
notice tat we have the only common factor is
(a+b)
so
a+b=11
we know that it is a POSITIVE integer
that means that it is from 1 to infinty, not including decimals or NEGATIVES
so like
1,2,3,4,5...
let's look at aour options
a+b=11
our choices are
a is
10,11,12
if we try a=10
10+1=11, yah true
if we try a=11
11+0=11
but 0 is not an integer
we can see that if we keep going to 12,14,15, we will get negative integers for b which is not allowed
a=10 is answer
It is a binomial and the degree of the binomial is 3.
<u>Step-by-step explanation:</u>
x² - 9x³
- There are only 2 terms in the polynomial, so it is termed as binomial
- If a polynomial contains three terms, then it is trinomial
- If a polynomial has 4 or more than 4 terms then it is termed as polynomial.
- Degree of the polynomial can be found by observing the terms with the highest exponent or power on the variables.
- Here the degree of the polynomial is 3, since the highest power of the expression is 3.
