Answer:
B
Step-by-step explanation:
Given
x² + 3x + 2 = 0
To factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are 2 and 1, since
2 × 1 = 2 and 2 + 1 = 3, thus
(x + 2)(x + 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1

Answer:
one cup of coffee costs $2, while one bottle of water costs $1
Step-by-step explanation:
We can represent this using two equations:
- Variable <em>x </em>represents cups of coffee, and variable <em>y</em> represents bottles of water.
5<em>x</em> + 2<em>y</em> = 12
4<em>x</em> + 7<em>y</em> = 15
Your answer for the value of <em>x</em> and <em>y</em> should be
<em>x</em> = 2
<em>y</em> = 1
Therefore, one cup of coffee costs $2, while one bottle of water costs $1.
