Answer:
x= -8
Step-by-step explanation:
1/2x + 13=9
- move 13 to the other side
1/2x= 9-13
-simply 9-13
1/2x= -4
-multiply 2 on both sides
1x=-8
x=-8
Polynomials are not closed under division. When you divide polynomials it is possible to get quotients with negative exponents or with fractions that have exponents in the denominator, and neither of these could be included in polynomials.
-circumference is equal to pi×diameter, area is equal to pi×radius^2
-28.26÷3.14=9, 9÷2=4.5, 4.5×4.5=20.25, and 20.25×3.14=63.585
-rounded to the nearest hundredth, the answer is 63.59
First one is $16 and the second is $276.25
