Step-by-step explanation:

An equation and the first step in its solution are shown.

Equation: x2 + 3x – 9 = 0

Step 1: x2 + 3x + h = 9 + h



What value of h is used to solve the equation by the method of completing the square?

Answers

Answer:

The answer is either 1.5 or 0.667

Step-by-step explanation:

x2+3x-9=0

x2+3x=9

6x=9

x=1.5

or

x=667

the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

Given :

An equation and the first step in its solution are shown.

Equation: [tex]x^2 + 3x -9 = 0[/tex]

Step 1: [tex]x^2 + 3x + h = 9 + h[/tex]

In completing the square method , we take the coefficient of x  and divide it by 2  and then square it

coefficient of x is 3

divide it by 2 , so we get [tex]\frac{3}{2}[/tex]

Then we square it [tex](\frac{3}{2} )^2\\\frac{9}{4}[/tex]

Then we add it on both sides of the equation

[tex]x^2 + 3x + \frac{9}{4} = 9 + \frac{9}{4}[/tex]

So, the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

How many quarter, a pound burgers can Kristina make out
of 75 pounds of ground beef?
1

Answers

Answer:

1 quarter pound = 0.25 of a pound.

Give that:

Total amount of ground beef =  pound

From 3.5 pound of beef we have to make burgers using 0.25 pound of beef in one burger

We have to find how many burgers can be made:

We have to divide 3.5 pound by 0.25 pound

i.e,

⇒14 quarter pounds burger can be made.

Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef

Step-by-step explanation:

300

1/4 =one quarter so 75 x 4 =300
