Answer:
x=9,-1 and 
Explanation:
we have been given with the quadratic equation 
we compare the given quadratic equation with general quadratic equation
general quadratic is 
from given quadratic equation a=1,b= -8,c= -9
substituting these values in the formula for discriminant 
Now, to find the value of x
Formula is 
Now, substituting the values we will get
And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of
Step-by-step explanation:
the answer is D
this is because, 24 + 9 = 33
and (3×8 + 3×3 =33)
Answer:
(x-9)(x²+9x+81); it'll give a difference of cubes
Step-by-step explanation:
Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.
*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.
Answer:
1. right, 2. median, 3. range or the IQR
Step-by-step explanation:
Bria: 145 centimeters
Jayleen: 1.5 meters
I'm going to convert Jayleen's into centimeters:
1 meter has 100 centimeters
1.5 x 100 = 150 centimeters
so,
Bria:145 centimeters
Jayleen: 150 centimeters
So, Jayleen bought more fabric
