Answer: B
(2x + 6)^2 can be rewrote as (2x + 6)(2x + 6).
Multiply out to get 4x^2 + 24x + 36
Answer:
Rational number
Step-by-step explanation:
Any number that can be written as a ratio of two integers is a rational number.
In the question, you have the keyword 'ratio', meaning a comparison between two numbers. For example 1.5 can be expressed as the ratio between 3 and 2 (3/2), as a fraction.
<u>When a number cannot be expressed as a fraction, it's called an irrational </u>number. <u> The most famous irrational number of all would be pi (π). </u> You cannot express pi in a ratio between numbers, because it's too complicated, it's basically an infinite number without any periodicity.
Answer:
is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Step-by-step explanation:
Given the function

As the highest power of the x-variable is 3 with the leading coefficients of 1.
- So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.
solving to get the zeros

∵ 
as

so
Using the zero factor principle
if 


Therefore, the zeros of the function are:

is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Therefore, the last option is true.
Graphs are used to put numbers in a visual form, like a bar graph showing population growth over time. Their advantage is that it helps the viewer understand the situation by seeing it in a easier way.
