B. 7x^2 + 3x + 3
C. x^2 - 3x + 15
D. -x^2 7x + 15
number y if 2/5of y is 22
B. linear binomial
C. cubic binomial
D. quadratic monomial
The expression 3x + 7 can be matched with the name B. linear binomial.
To understand why this expression is classified as a linear binomial, let's break down the terms:
Linear: The expression is linear because it is a degree-one polynomial. The highest power of the variable 'x' is 1, and there are no other variables or exponents present.
Binomial: The expression is a binomial because it consists of two terms. In this case, the two terms are 3x (the first term) and 7 (the second term), connected by the plus sign.
A linear binomial represents a straight line when graphed on a coordinate plane, where the variable 'x' represents the horizontal axis, and the resulting expression represents the vertical axis. The term "binomial" indicates that there are two terms in the expression.
In conclusion, the expression 3x + 7 is a linear binomial because it is a degree-one polynomial with two terms: 3x and 7.
