Answer:
(-infinity, +infinity)
Step-by-step explanation:
Even tho' f(x) = 5x has only one term, it's still classified as a polynomial. All polynomials are defined on all x: (-infinity, +infinity).
Answer:
it is 5/12
Step-by-step explanation:
5+5+5+5= 20
12+12+12+12=48
<span>solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.</span>
Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).
Answer:
the perimeter of is 32 cm
Step-by-step explanation:
of the perimeter is 32 and the base is 12. then the other two sides are both 10 cm.
