Answer:
<h2>x = 129</h2>
Step-by-step explanation:
Domain of the function is x in order pair for example (2,3) 2 is the domain
Answer:
the cubes are 1 in on all sides
but...
since there's gaps its more likely that there a 1/2 in or 3/4 in
Step-by-step explanation:
12/12=1
Answer:
Step-by-step explanation:
General form of quadratic equation:
ax^2+bx+c=0
ax^2+bx=-c
To complete the square, we will divide the coefficient of x in the general quadratic equation as written above and divide by 2
I'm the question;
x^2-20x+13=0
x^2-20x=-13
The coefficient of x =-20
Divide the coefficient by 2 and square the result afterwards
-20/2= - 10
(-10)^2= 100
Add 100 to both sides of the equation
x^2-20x+100=-13+100
x^2-20x+100=87
x^2-10x-10x+100=87
x(x-10)-10(x-10)=87
(x-10)(x-10)=87
(x-10)^2=87
Answer is 10,87
