P = 6
Q = 15
How to solve:
Note the equal sign. This means that both expression's out come must equal each other. For that to happen, everything inside both expressions must equal each other. In this case:
6x + Q = Px + 15; 6x + 15 = 6x + 15

Answer:
22.77°
Step-by-step explanation:
Using SOH CAH TOA trigonometry identity
Height of the building (opposite side) = 172ft
Length of the shadow (hypotenuse) = 444ft
Using SOH
sin theta = opp/hyp
Sin theta = 172/444
Sin theta = 0.387
theta = arcsin0.387
theta = 22.77°
Hence the angle of depression is 22.77°
Answer:
Mauricio needs 10.5 liters of oil for frying.
Step-by-step explanation:
It is given that,
Mauricio can fry 6 potatoes using 1 liter of oil.
So, he can fry 18 potatoes using 
= 3 liters of oil.
Thus, Mauricio fries 18 potatoes using 3 liters of oil per hour
Now, Mauricio wants to fry the 18 potatoes for 3.5 hours.
So, the total amount of oil needed by him = 3.5 × 3 = 10.5 liters.
Hence, Mauricio needs 10.5 liters of oil for frying.
Answer:
y = - 4, y = 0
Step-by-step explanation:
Given
y² + 4y = 0 ← factor out y from each term on the left side
y(y + 4) = 0 ← in factored form
Equate each factor to zero and solve for y
y = 0
y + 4 = 0 ⇒ y = - 4
