Discriminant for the quadratic equation  2x^2+x-3=0 is d=25

How to find the d Discriminant of the quadratic equation ?

We know that the standard quadratic equation

ax^2+bx+c=0

Discriminant of the equation is d=b^2-4ac

Equation given in the question is

2x^2+x-3=0

So we can find the values of a,b,c

a=2\\b=1\\c=-3

Substitute the values

d=1^2-4*2*(-3)\\d=1+24\\d=25

Sammy buys 5 pounds of oranges for 7.50 at this rate how much would 8 pounds of oranges cost
Nadusha1986 [10]

The cost of 8 pounds of oranges based on the total cost of 5 pounds bought is 12.00

What is the cost for a pound of oranges?

The cost of a pound of oranges based on the rate at which 5 pounds were bought and 8 pounds would also be bought is determined as the amount paid for 5 pounds of oranges divided by the number of pounds of oranges bought

cost per pound of oranges=cost of 5 pounds/5 pounds

cost per pound of oranges=7.50/5

cost per pound of oranges=1.50

Based on the 1.50 per pound, the cost of 8 pounds is the cost per pound multiplied by 8 pounds

cost of 8 pounds of oranges=1.50*8pounds

cost of 8 pounds of oranges=12.00
