Answer:
A. 10x^2 +53x +63
B. degree 2; quadratic trinomial
C. the result of the multiplication of polynomials is a polynomial
Step-by-step explanation:
<h3>Part A:</h3>
The area is the product of length and width. The distributive property is useful for simplifying the expression.
A = LW
A = (2x +7)(5x +9) = 2x(5x +9) +7(5x +9)
A = (10x^2 +18x) +(35x +63)
A = 10x^2 +53x +63 . . . . area expression
__
<h3>Part B:</h3>
The highest power of x is 2. There are 3 terms. A degree-2 polynomial is called a "quadratic." A 3-term polynomial is called a "trinomial."
- degree 2
- quadratic trinomial
__
<h3>Part C:</h3>
In part A we multiplied two polynomials and came up with a result that is a polynomial. This suggests polynomials are closed with respect to multiplication.
L+L+(L-4)+(L-4)=72
4L-8=72
4L=80
L= 20
so W= 20-4 or 16
Hello.
Firstly, 4 percent of 100 is 0.04 percent, and given the equation y = 3000(1 + 0.03)^n, you replace the 0.03 with 0.04.
Therefore, the answer is C, y = 3000(1 + 0.04)^n.
Answer:
The number -7.45 is not an integer but a rational and real number.
So the answer is C
Step-by-step explanation:
What -7.45 is:
Real numbers: Real numbers can be positive or negative and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers.
Rational numbers: In Maths, a rational number is a type of real number in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number. Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on.
What -7.45 is not:
Integer: a whole number; a number that is not a fraction.
I hope this helps!
