Answer:
literally google graphing calculator and type 3x
Answer:
D.
Step-by-step explanation:
A term in a polynomial is a single number or a number multiplied by any number of variables. A polynomial is a sum of terms.
The only thing that can be done with variables in a polynomial is to multiply them by numbers or other variables. In a polynomial, you cannot: divide by a variable (have a variable in a denominator), have a root of a variable, have a log of a variable, have a variable as an exponent, etc.
All expressions are polynomials except for D. In D., the negative exponents mean division by variables.
Let's say David's age right now is x years
x + 6 = 2(x - 7)
x + 6 = 2x - 14
x = 20
Therefor David is 20 years old
the value is
1.2r-11.3r=40
-10.Ir=40
r=40/-10.1
r=-0.2525
hope this helps :):):)
15 x 7 days = 105 then multiply 5 weeks. 5 x 105 = 525 miles
