Answer:
D
Step-by-step explanation:
The parabola opens up. Which means the vertex is the minimum value.
Answer:
explanations: we multiply with a rational surd
(x-9)*√(x+9)/(√(x-9)*√(x+9)
=(x-9)√(x+9)/

B.( x-9)/√x+3 =( x-9)*(√x-3)/(√x+3)*(√x-3)
= (x-9)*(√x-3)/x-9
=√x-3
Answer:
1.04 liters
Step-by-step explanation:
If 50 is 4liters
Then 13 is x
Use this below equation
Value t is for value y then how much for value z

X = 4/50 *13
X = 1.04liters
Or
13/50 = x/4 (cross multiply)
50X = 52
X = 52/50
X = 1.04 liters
Answer:

Step-by-step explanation:
Given:
'C' represent total cost of lease. 'd' represents cost of sales in dollars.
Cost of 1 square foot of building = $0.75
Total area of the building = 500 square feet.
Sales tax on the total sales = 2.5%
Now, cost of 500 square feet area = Cost of 1 square foot × Total area
Cost of 500 square feet area = 
Now, sales tax is 2.5 of total sales 'd'. This gives,
Sales tax = 
Now, total cost is the sum of least amount and total sales tax.
Total cost = Least amount + Sales tax
⇒
