A quadratic equation is written in the form 
Looking at the second, third, and fourth options, we see that the highest powers are greater than two, which automatically disqualifies them from being quadratics (since the highest power in a quadratic is 2).
This makes the first option the correct choice since the expansion of the equation gives 
Linear Equation
A linear equation is any equation involving one or two variables whose exponents are one. In the case of one variable, one solution exists for the equation. For example, with 2x = 6, x can only be 3.
Linear Inequalities
A linear inequality is any statement involving one or two variables whose exponents are one, where inequality rather than equality is the center of focus
Answer:
35.6%
Step-by-step explanation:
31/87(100)
3100/87
35.6%
11. 10^-8 = 1 • 10^-8 in decimal form
12. 6 • 10^-4 = 0.0006 in decimal form
13. n^m turns into 5^4
5 • 5 • 5 • 5 = 625
5^4 = 625
Answer:
$20.22
Step-by-step explanation:
You multiply 18.99 with 0.065 to see how much extra money you have to pay. Then you add it back to 18.99 for the final cost.
