Answer:
-2, and 3
Step-by-step explanation:
-x² +x +6 = 0 is the same as
x²-x-6=0
but, x² -Sx+P=0
think what 2 numbers have the sum =1 and product = -6 that will be -2 and 3 witchh are your zeros
or you can use the graph or quadratic formula to solve
Answer:
14.4 miles
Step-by-step explanation:
5 goes into 18 3.6 times and 3.6 x 4 = 14.4, she can run 3.6 miles per hour
P = a + b + c where a < b < c
P = 42 in
b = 18 in
a = x
c = 4x - 1
The equation:
x + 18 + 4x - 1 = 42 |combine items
5x + 17 = 42 |subtract 17 from both sides
5x = 25 |divide both sides by 5
x = 5 (in)
c = 4 · 5 - 1 = 20 - 1 = 19 (in)
Answer: The length of the longest side is 19 in.
Using it's concept, it is found that the domain for the expressions is, respectively, given by:
![x \neq 0, x \neq 0, (-\infty, \infty), (-\infty, \infty), x \neq 2](https://tex.z-dn.net/?f=x%20%5Cneq%200%2C%20x%20%5Cneq%200%2C%20%28-%5Cinfty%2C%20%5Cinfty%29%2C%20%28-%5Cinfty%2C%20%5Cinfty%29%2C%20x%20%5Cneq%202)
<h3>What is the domain of a function?</h3>
It is the <u>set that contains all possible input values</u>.
In a fraction, the denominator cannot be zero, hence:
- The domain of the first two expressions is of
.
- The domain of the last expression is of
.
The third expression can be simplified, as:
(x + 5)/(x + 5) = 1.
The same is true for the fourth, as:
x²/x = 1.
Neither has any restriction, hence their domain is all real numbers, represented by
.

The answer is that they are congruent.
