√j+√j+14=3√j+10
2√j+14=3√j+10
minus 2√j both sides
14=√j+10
minus 10 both sides
4=√j
squaer both sides
16=j
answer is D, 16
Each additional hour or rental costs $25.
Step-by-step explanation:
Given equation is;
4h+150=250 Eqn 1
Where 150 is the cost for first 2 hours and 4h is the cost for remaining hours.
Total cost = $250
Solving Eqn 1
Subtracting 150 from both sides
Dividing both sides by 4
Each additional hour or rental costs $25.

Answer: (x+5)^2+(y-2)^2=81
Step-by-step explanation:
Answer:
Step-by-step explanation:
(-9+2)/2= -7/2= -3.5
(8 + (-1))/2 = 7/2= 3.5
(-3.5, 3.5) is the solution
Let us assume the first even number = n
The second consecutive even number = n + 2
The third consecutive even number = n + 4
The addition of the three consecutive even numbers is 42 and it is already given in the question. Based on the information's given in the question, the answer can be easily deduced.
Then, the equation can be written as
n + (n + 2) + (n + 4) = 42
3n + 6 = 42
3n = 42 - 6
3n = 36
n = 36/3
= 12
So
The first even number = 12
The second consecutive even number = n + 2
= 12 + 2
= 14
The third consecutive even number = n + 4
= 12 + 4
= 16
So the three consecutive even numbers are 12, 14, 16.
