<span>3x^2 + 18x + 15 = 0
15 + 18x + 3x2 = 0
3(5 + 6x + x2) = 0
</span>3((5 + x)(1 + x)) = 0
5 + x = 0
5 + -5 + x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + x = 0 + -5
x = 0 + -5
x = -5

Answer: I honestly have no clue
Step-by-step explanation:
Answer:
14°F
Step-by-step explanation:
We are given that,
The label for the high temperature is -10°C.
It is required to label the alarm in Fahrenheit (°F).
As we know,
(1°C × 
) + 32 = 33.8°F
Thus, for -10°C, we have,
(-10°C × ) + 32 = -18 + 32 = 14°F
Hence, the Fahrenheit value on the label will be 14°F.
It should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
<h3>How to illustrate the information?</h3>
It should be noted that an equation is used to show the relationship that occur between the variables that are illustrated.
In this case, it should be noted that the equation
(ac+b-d)(a² - c) will be solved accordingly. This will be:
(ac+b-d)(a² - c)
Open the parentheses
a³c + ac² + a²b - bc - a²d + cd
Therefore, it should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.

Answer:
He worked 40 regular hours.
He 4 hours beyond 40.
He worked 40 + 4(1.5) = 40 + 6 = 46 adjusted hours
Step-by-step explanation:
John worked 44 hours and a regular work week is 40 hours. This means John worked 40 regular hours plus 4 hours over time. He receives time and a half or 1.5 for each hour over 40.
So 40 + 4(1.5) = 40+6=46 adjusted hours.
