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