Answer:
x= 
- 
Step-by-step explanation:
Selections 2, 3, 5, 6 are polynomials.
1 and 4 are not. The coefficients don't have to be integers, but the powers of the variables need to be positive integers. In 1, you have x^-1. in 4, you have x^(1/2).
5x5x5=125
12x3=36
36x3=108
108+125=233
233in^3 is the answer
Answer:
they each share the same variable which is raised to the same exponent, 1
Step-by-step explanation:
Answer:
1.19
Step-by-step explanation:
You're trying to figure out what x is here.
So you'll want to isolate the x. That means, get it alone.
Since both sides are equivalent, when you subtract 2.45 from the x side, you also subtract it from the other side too.
x = 3.64 - 2.45
x = 1.19
