Using iready the tutorial does not count as a grade and if your worried about passing the test turn your wifi off count to 10 then click the answer you think is right, if it is right turn wifi back on and click next, if wrong click next and it will kick you out of it then turn wifi back on and go back onto the lesson and repeat until you have the right answer, I always got 100% on my quizs this way
Answer: 43,45,47.
Step-by-step explanation:
I think the correct answer from the choices listed above is the second option. Solving a 6 order system <span>would be the process that is used to describe solving a system of equation with 6 variables. The number of variables should be equal to the order of the system for it to be solved. Hope this answers the question.</span>
Step-by-step explanation:
We khow the sum and the product of the zeroes of this quadratic polynomial
Here is a trick :
when we khow the sum S and the product P ofvtwo numbers we can find them by solving :
x²-Sx+p=0
here S= -8 and P=12
so:
x²+8x+12=0
Let Δ be the discrminant of this equation: a= 1 , b= 8 and c=12
Δ= 8²-4*12 =16
the zeros are:
(-8-4)/2= -6
(-8+4)/2 = -2
verify:
-6+(-2)= -8
-2*(-6)= 12
now the polynomial quadratic is:
(x+6)(x+2)
