Answer:
D) x=
Step-by-step explanation:
The quadratic formula is : 
A in terms of this question=9
B in terms of the question is 12
C in terms of the question is -24.
This question is an example of a quadratic equation. To work this out you may first need a calculator. The first step is to substitute the values of a,b and c into the formula. So once substituted the formula of
becomes
. Although when written in a calculator there will not be a plus and minus button and so you would have to do this separately.
However when substituting the values it would be best practice to put them in brackets.
1) Substitute the values into the equation for +.

2) Substitute the values into the equation for -.

Your equation would be t +25=57 because we don’t know how many necklaces Stacy made so we use T to plug it in and solve
Answer:
C: 9
Step-by-step explanation:
The highest power in the polynomial is 9.
1:100 because 20 divide by 20=1 and 2000 divide by 20 =100
65754.6 because the 9 in the hundreds place bumps up the five in the tenths
