Answer:
<h3>
-2a³ + 9a² + 6ab² + 45a + 18b² </h3>
Step-by-step explanation:
(a + 3)×(−2a² + 15a + 6b²) =
= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =
= -2a³ + <u>15a²</u> + 6ab² - <u>6a²</u> + 45a + 18b² =
= -2a³ + 9a² + 6ab² + 45a + 18b²
Answer
Elena must have substracted 1/2x from both sides of the equation.
Lin must have multiplied both sides of the equation by 2
Explanation
The equation given is

For Elena to have arrived at

Then Elena must have substracted 1/2x from both sides of the equation.
That is;

For Lin to have arrived at

It shows Lin must have multiplied both sides of the equation by 2
That is;
B and e I think I don’t know tho
Answer:
A.
Step-by-step explanation:
Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

Now take out the common factors,

Thus, the correct option is choice (A).
A tenth is 1/10.
5 tenths is 5/10.
5/10 is a fraction that can be made simpler, by dividing by 5, so that the fraction becomes 1/2.
1/2 is a half, so if you have a half a dollar, you have 50 cents.
