Answer:
50
Step-by-step explanation:
Because the first digit can only be odd, there are 5 possible numbers
(1, 3, 5, 7, and 9)
The second digit can be any number because they didn't really say anything about it, meaning there are 10 possibilities (REMEMBER! you can use 0 as the 2nd digit in a number! Just not as the first)
0 -> 9
So, 5 x 10 = 50

Jiri is 64 years old!
F(x) = 4x - 1
g(x) - 2x² + 3
<u>(f · g)(x)</u>
(f · g)(x) = (4x - 1)(2x² + 3)
(f · g)(x) = 4x(2x² + 3) - 1(2x² + 3)
(f · g)(x) = 4x(2x²) + 4x(3) - 1(2x²) - 1(3)
(f · g)(x) = 8x³ + 12x - 2x² - 3
<u>(f/g)(x)</u>
(f/g)(x) = <u>4x - 1</u>
2x² + 3
<u>(g/f)(x)</u>
(g/f)(x) = <u>2x² + 3</u>
4x - 1
(g/f)(x)= ¹/₂x + ¹/₈ + <u> 3¹/₈ </u>
4x - 1
