Answer:

b = 12mm

Step-by-step explanation:

Using pythagoras theorem, you will be able to find the answer.

a² = b² + c²

b² = 15 ² - 9²

b² = 144

b = \sqrt{144}

∴ b= 12mm

Help algebra 2 please

Answer:

option 4

Step-by-step explanation:

(f*g)(x) =(x² + x+ 1)*(x² - x -1)

           = x²*(x² - x -1)   + x(x² - x -1) + 1*( x² - x -1)

            = x²*x² - x²*x -x²*1   + x*x² - x*x -x*1 + x² - x -1

            = x⁴ - x³ - x² +x³ - x²  - x  + x² - x -1

           = x⁴  - x³ + x³  - x² - x² + x² - x - x - 1

       = x⁴ - x² - 2x - 1
