No Nothing Further Can Be Done
Rewrite the decimal number as a fraction with 1 in the denominator
0.225=0.22510.225=0.2251
Multiplying by 1 to eliminate 3 decimal places, we multiply top and bottom by 103 = 1000
0.2251×10001000=2251000
Answer:
Choice b.
.
Step-by-step explanation:
The highest power of the variable 
in this polynomial is 
. In other words, this polynomial is quadratic.
It is thus possible to apply the quadratic formula to find the "roots" of this polynomial. (A root of a polynomial is a value of the variable that would set the polynomial to 
.)
After finding these roots, it would be possible to factorize this polynomial using the Factor Theorem.
Apply the quadratic formula to find the two roots that would set this quadratic polynomial to . The discriminant of this polynomial is 
.
.
Similarly:
.
By the Factor Theorem, if 
is a root of a polynomial, then 
would be a factor of that polynomial. Note the minus sign between and 
.
- The root
corresponds to the factor 
, which simplifies to 
. - The root
corresponds to the factor 
, which simplifies to 
.
Verify that 
indeed expands to the original polynomial:
.
Answer:
Is there answer choices?
Step-by-step explanation:
Not very clear, could be any number of things. If there are words to choose from i can help you.
First, subtract 90° from 180°, since 180<span>° is the sum of all the angles in a triangle.
180 - 90 = 90</span><span>°.
Now, we can really just test out different sets of numbers in a 2:7 ratio until we find two that have a sum of 90</span><span>°.
If you look closely, 2 + 7 is 9. So, using that logic, multiplying 2:7 by 10 would get you 20</span>° and 70°, which have a sum of 90<span>°.
So the measures of the missing 2 angles is 20</span>° and 70<span>°.
Hope I helped!</span>
