The value of the expression in the form a(x+b)^2 is 1.5(x+2)^2 - 4
<h3>Vertex Form of a quadratic expression</h3>
Given the quadratic expressions
1.5x^2+6x+......
1.5(x^2 + 4x)
Using the completing the square method
The coefficient of x = 4
Half of the coefficient = 4/2 = 2
The square of the result = 2^2 = 4
The equation is expressed as:
f(x) = 1.5(x^2+4x+ 4) - 4
f(x) = 1.5(x+2)^2 - 4
Hence the value of the expression in the form a(x+b)^2 is 1.5(x+2)^2 - 4

Answer:
5.50
Step-by-step explanation:
If three cones cost 8.25, then each cone should cost 2.75. (8.25 / 3 = 2.75)
Then 2 cones should cost 5.50 (2.75 x 2 = 5.50)
Answer:
$7.50
Step-by-step explanation:
Sara buys a sweater that costs $30
The store is having a 25% off sale.
To figure out what 25% is you do 25/100, which will give you 0.25,
Multiply 0.25 by $30
You should get $7.50.
