Answer:
<h2>Equation </h2>
.In mathematics, the term equation means a statement of equality. It is a sentence in which two expressions are placed equal to one another. In order to satisfy an equation, it is important to determine the value of the variable concerned; this is known as solution or root of the equation.
<h2>Expression</h2>
if it does not contain an equal to (=) sign, then it is just an expression. It carries numbers, variables and operators, that are used to show the value of something. Go through this article to understand the basic differences between expression and equation.

Assuming that 10% is the probability of a switch being defective (since left-handedness has nothing to do with the problem):
For a binomial distribution, probability(r out of n) = (nCr) (p)^r (q)^(1-r)
p = 10% = 0.1, q = 1 - p = 0.9
r = 2 switches, n = total of 12 switches
probability = (12C2) (0.1)^2 (0.9)^(12-2)
probability = 66(0.1)^2 (0.9)^10
probability = 0.23
Answer:
![11x + 13](https://tex.z-dn.net/?f=11x%20%2B%2013)
Step-by-step explanation:
![1. \: (8x + 3x) + (10 + 3) \\ 2. \: 11x + 13](https://tex.z-dn.net/?f=1.%20%5C%3A%20%288x%20%2B%203x%29%20%2B%20%2810%20%2B%203%29%20%5C%5C%202.%20%5C%3A%2011x%20%2B%2013)
In radical form, the shortest distance from ( -4 , 4 ) and the line y = -2x + 6 is
2√5 units.
