The coefficient of (3y² + 9)5 is <u>15</u>.
A polynomial is of the form a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ₋₁x + aₙ.
Here, x is the variable, aₙ is the constant term, and a₀, a₁, a₂, ..., and aₙ₋₁, are the coefficients.
a₀ is the leading coefficient.
In the question, we are asked to identify the coefficient of (3y² + 9)5.
First, we expand the given expression:
(3y² + 9)5
= 15y² + 45.
Comparing this to the standard form of a polynomial, a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ₋₁x + aₙ, we can say that y is the variable, 15 is the coefficient, and 45 is the constant term.
Thus, the coefficient of (3y² + 9)5 is <u>15</u>.

Answer:
21x - 36
Step-by-step explanation:
that's just assuming that you only need to simplify the answer and not solve it.
My work shown is how to get x. now that you have x plug it into the equation.
To test your answer add both 51 and 39, and you should get 90 (the measurement of a right angle)
Answer:
C
Step-by-step explanation:
When we talk of domain, we are referring to the values we have on the x axis
By considering the range of values we have on the x-axis, we have the domain we want
We have the gymnast complete the sessions in 95 seconds.
This means that the highest point on the x-axis is 95 seconds
But how do we measure time? we do this in form of integers
So the correct domain will be all
integers between 0 and 95
which can be represented as 0≤x≤95
