8 0

Answer:

x² + 2x - 15 = 0

x² + 2x + 1 = 16

(x + 1)² = 16

You can then go forward with that to solve it:

x + 1 = √16

x = -1 ± √16

x = -1 ± 4

x = 3, -5

A palindrome is a number or a word that is the same in the two directions: left to right and vice versa. Example of palindromes:
monitta

Answer:

900

Step-by-step explanation:

None of the numbers beginning with 8 are palindromic. There aren't very many numbers that are that are also 5 digits long.

The first digit cannot be 0 (otherwise you will wind up with a 4 digit number)

The first digit can be 9 others.

The second digit can be all 10 digits

The third digit can also be all 10 digits.

The first digit and the 5th digit must be the same so the fifth digit does not add anything new or more palindromic numbers.

The 2nd and 4th must also be the same.

So the total number of palindromic numbers that are 5 digits long

9 * 10 * 10 = 900

There really aren't any more.

80908 is one example of a palindromic 5 digit number.

<em><u>Answer: x=2</u></em>

Explanation:

Subtract by 2 both sides of an equation.

2-8x-2=-14-2

Simplify.

Then, you divide into the -8 from both sides of an equation.

-8x/-8=-16/-8

Simplify.

16/2=8

*It change positive to negative sign.*

x=2

Hope this helps!
