Answer:

The answer to your question is 9.  (2x - 3)(3x - 4)      10.   (x + 4)²    

Step-by-step explanation:

9.               6x²  -  17x + 12

-Multiply 6 by 12 and find the prime factors of the result

              6 x 12 = 72

                                  72   2

                                  36   2

                                   18   2

                                     9  3

                                     3  3

                                      1

-Find two numbers that added gives -17

-These numbers are -8 and -9

-Substitution

                    6x² - 9x - 8x + 12

-Factor by grouping

                   3x(2x - 3) - 4(2x - 3)

                   (2x - 3)(3x - 4)    

10.                x²  + 8x  + 16

-Find two numbers that added gives 8 and multiply gives 16

-These numbers are 4 and 4

-Factor like a perfect square trinomial

                  (x + 4)²

Answer:

Equation: 30=2(x-2)+2(2x+3)

x:\frac{14}{3}

Step-by-step explanation:

By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.

Knowing this, you can write the following equation:

P=2(x-2)+2(2x+3) <em> [Equation 1]</em>

According to the data given in the exercise, the perimeter in feet of the fighter is:

P=30

Therefore, you can substitute this values into<em> [Equation 1]:</em>

30=2(x-2)+2(2x+3)

Finally, you must solve for "x" in order to find its value. This is:

30=6x+2\\\\30-2=6x\\\\\frac{28}{6}=x\\\\x=\frac{14}{3}

180° - 36° - 39° - 33° = <u>7</u><u>2</u><u>°</u>

x° = 180° - 72°

x° = <u>1</u><u>0</u><u>8</u><u>°</u>

So, the value of x is 108°
