Evaluate the following expression, when x=-2 2x^2+4x-3

A) 3
B) 3
C) -19
D) 9

Step-by-step explanation:

To find the value of this equation when , we can substitute this value inside the equation and use PEMDAS to successfully find the value.

With the expression of , let's substitute -2 in as x.

Now let's follow PEMDAS to solve this equation.

PEMDAS states that when solving an expression/equation, the order we must follow is

We can now solve for this.

We see that exponents come before multiply and dividing. Therefore:

So the value of our first term is 8.

Our second term will be , and our last term will remain -3.

Adding these values together:

Therefore, the value of this expression when x = -2 is -3.

Hope this helped!

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45
