The value 2.75 goes in the first box, since it's the first term.
The expression goes in the second box. The second line says "to get the nth term, we multiply the previous term by 0.69"
Answer: B, D, E
Step-by-step explanation: Its very easy to check, For B, you notice that it is the same, only the numbers are swapped. In multiplication, this is perfectly fine. For D, I just knew that the answer was 12x+9. And in D, there are 3 4x and 3 threes', so that one was correct. And for E, all you have to do is to multiply accordingly to the distributive property
The value -0.07 is the negative real number in the quadratic equation 0 = x² – 5x – 4
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have a quadratic equation;
0 = x² – 5x – 4 or
x² – 5x – 4 = 0
Here a = 1, b = -5, and c = -4
After simplification:
x = 5.70 or x = -0.70
The value x = -0.70 is the negative real number.
Thus, the value -0.07 is the negative real number in the quadratic equation 0 = x² – 5x – 4
