What are the terms in the expression 7x+4y+1
2 answers:
Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Since there are 3 terms in the expression:
First term is 7x.
A term x with coefficient 7.
Second term is 4y.
A term y with coefficient 4.
Third term is 1 i.e constant term.
So, the respective three terms would be 7x, 4y, and 1.
Hence, Option 'd' is correct.

Answer:
All of them are polynomials except c.
Step-by-step explanation:
Polynomials are in the form:
You can see here there are no extra symbols like square root, cube root, absolute value, and so on on the variable x...
We also don't have division by a variable. All the exponents are whole numbers.
a) While it has a square root, it is not on a variable so a is a polynomial. The exponents on the variables are whole numbers.
b) b is a polynomial also because all the exponents are whole numbers.
c) This is not a polynomial because there is a square root on a variable.
d) This is a polynomial. All the exponents are whole numbers.
Answer:
Step-by-step explanation:
The equation of a circle:
(h, k) - center
r - radius
We have the center (4, -3) and the point on the circle (9, -3).
The length of radius is equal to the distance between a center and an any point on a circle.
The formula of a distance between two points:
Susbtitute:
The center (4, -3) → h = 4, k = -3.
Finally we have:
