PEMDAS comes first. Instead of adding 9+2 first, they should've multiplied 2x3. The final answer would be 15.
1800 - 1350= 450 3 months after the purchase he payed $450
450/3= $150 per month
1350 - 1050= 300 5 months AFTER THE PURCHASE he payed $300
300/2= $150 per month
^after 2 more months he payed $300^
$150 per months
Equation: (initial amount) - (150)M
M= amount of months after purchase
B = 1800 - 150M
The correct option is the third one.
y = -√(x - 5) + 3
<h3>Which function has a domain of x>5 and a range of y≤3?</h3>
Remember that a square root can only be evaluated in values equal or larger than zero.
So, if we want the domain to be x > 5, then we must have:
√(x - 5)
Now we also want the range to be equal or smaller than 3, then we should have a constant term equal to 3, and a negative coefficient before the square root, then we get:
y = -√(x - 5) + 3
So the correct option is the third one.

Answer:
A = 172.0 in²
Step-by-step explanation:
Exterior angle of any side is 360 / 5 = 72°
Interior angle between any two adjacent sides is 180 - 72 = 108°
A regular pentagon can be thought of as 5 isosceles triangles with two common angles of 108 / 2 = 54°
The height of each triangle is
h = (10/2)tan54
The area of each triangle is ½(10)h = ½(10)(10/2)tan54 = 25tan54
The area of the pentagon is
A = 5(25tan54) = 125tan54 = 172.04774005...
A = 172.0 in²
