Answer:
Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.
Step-by-step explanation:
The exponent of variables in a polynomial should be natural numbers (
, 
, 
, 
, 
.)
is equal to 
. In this expression, 
is the variable. Its exponent is 
, which isn't a natural number.
- On the other hand,
is equivalent to 
. The exponent of variable is , which is indeed a natural number.
isn't a polynomial because the exponent of variable isn't a natural number. On the other hand, is indeed a polynomial over the set of real numbers.
Answer:
# 1,3 and 6
Step-by-step explanation:
Answer:
4cm
Step-by-step explanation:
Given data
L=(2x+3)
W=(x-1)
P=28cm
A= L*W
A= (2x+3)*(x-1)
open bracket
A= 2x^2-2x+3x-3
collect like terms
A= 2x^2+x-3
P= 2L+2W
P= 2*(2x+3)+2(x-1)
P= 4x+6+2x-2
collect like terms
P= 6x-4
but p= 28
28= 6x-4
28-4= 6x
24= 6x
x= 24/6
x= 4cm
Hence x= 4cm
Answer:
b
Step-by-step explanation:
To find the average rate of change, evaluate the function at the given points.
Evaluate the difference of the function at the given points.
Divide the difference of the function at the given points with the difference of the given points.
