You can use the <u>determinant</u><u> (square root)</u> of a quadratic equation to determine the number and type of solutions of the equation.
> 0 → 2 real solutions
- if is a perfect square, then rational sol'ns
- if is not a perfect square, then irrational sol'ns
= 0 → 1 real solution (double root)
< 0 → 2 imaginary(complex) solutions
Answer:
72+35=107cm^2
Step-by-step explanation:
(8*9)+(5*7)=107
The greatest common factor for 130 would be 130.
Factors of 130
1, 2 , 5 ,10,13, 26, 65 and 130
A factor is a number <span>that is multiplied with another produces a given number or expression. Lets look at factors of 16</span>
1x16 = 16
2 x 8 = 16
The factors are 1,2,8,16. When we multiply them we get 16. Also each one of these factors divide into 16 evenly too.
the number of cards in my friends stack is 20 total cards
Answer: x = 3
Step-by-step explanation:
5x - 1 + 14 - original equation
5x = 15 - add 1 to both sides
x = 3 - divide both sides by 5
