This is your answer and shows how to do it
Answer: 348 and 355
Step-by-step explanation:
Let two positive numbers are x and y
so,
when the difference is 7 then equation will become
x-y=7 Eq(1)
when product is 2439 then equation will become
x*y=2438 Eq (2)
By rearranging Equation (2)
x= 2438/y Eq(3)
Now put the value of x as in eq (3) in eq(1) to get y's value
(2438/y)-y=7
(2438-1)/y =7
2437 / y =7
2437/7 =y
y=348.14 approx 348
Put the value of y in Eq(1) for x
x-348=7
x=7+348
x=355
so the two positve numbers are 355 and 348
For Check
x-y=7
355-348=7
7=7
The correct answer is D. If a number is not divisible by two, then it is an odd number

Binomial
Bi means two. So you have 2 terms in a binomial. x^2 + 2 is a binomial. In this example, they cannot be added. There is one sign between the 2 terms. In this case a plus sign.
You have a binomial in the question's table. It is 3x - 9. 2 terms 1 sign.
Trinomial
Tri means three. You have 3 terms in a trinomial. You normally have 2 signs (at least) but you could have 3. All the terms are unlike.
x^2 + 2x - 1 is a a trinomial.
You have 1 trinomial in your question.
y = - 3x^2 - 6x + 9
This has 3 signs which is not normal but it is not unique.
Monomial
Mono means one. You have two monomials in your question.
2x^2 and - 2 Yes a constant can be a monomial.
Quadratic.
A quadratic has very specific properties.
The highest power of a quadratic must be x^2.
x^2 + 3x + 2 is a quadratic.
3x^2 - 4x + 2 is a quadratic.
-2x^2 - 5x + 3 is a quadratic.
x^2 + 5 is a quadratic.
- 2x^2 is a quadratic.
A quadratic may or may not have a linear term as in 3x
A quadratic may or may not have a constant term [yet to be defined]
Linear
A linear equation must have 1 on the variable on both sides of the equal sign.
y = 3x is linear
y = 3x + 7 is linear.
y + 3 = 3x + 2 is linear. The 3 can be put on the right by subtracting 3 from both sides.
y = 2x - 1
y= 3x - 9 is a linear equation.
When you graph 3x - 9 you get a straight line.
y = 3x - 9, you get a straight line. Go to desmos and try it.
Constant.
Has no variables associated connected to it although a line can consist of a constant on one side.
3 is a constant.
34 is a constant.
y = 8 is constant. It is a line that is parallel to the x axis going through 8.
0 is a constant.
y = 0 is the x axis.
Exponential
is a constant raised to a variable power.
y = 3^x. You don't have one of these.
Naming by power.
You have two equations that are raised to the power of 2.
One is the first monomial
the second is the last one.
One has a power going to 1 ( the third one)
What's the power on the constant.
Okay so here it is
the answer is M=100D + 200
Why?
because 200miles divided by 2 days is 100 so every day she drives 100 miles which means you would times the days by 100 miles and since you have already gone 200 miles it would be
m=100d+ 200
hope this helps
