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:
u transpose all the constans to one side of the '=' sign and solve
Step-by-step explanation:
for example,
in the first question
the sides of the triangles are proportional then,
25/30 = x/ 10
=> (25x10)/30 = x
=> 250/30 = x
=> 8.33
im pretty sure like this u can do the rest, ;)
C) because the 7 and x right next to each other represents multiplication. so it's:
7x=91
7X(Allison's money)=91
Simple count by 2's to tens
