BOYS AND GIRLS, HELP ME PLEASE!!
5,6,7,8 PLEASE
factor this examples

Step-by-step explanation:

5) 4a² + 8ac = 4a*a + 4*2*a*c  

                    = 4a(a + 2c)   {Take the common factor}

6)3m² - 6mn = 3*m*m  - 3*2*m*n

                      = 3m(m - 2n)

7)ab - ac + yb - yc = (ab - ac) + (yb - yc)   {Group}

                              = a(b - c) + y*(b -c)

                              = (b -c)(a + y)

8) ab + ac + xb + xc = (ab + ac) + xb +xc

                                = a(b + c) + x(b + c)

                                 = (b + c)(a + x)

5) 4а²+8ас=4а(а+2с)

6) 3m²-6mn=3m(m-2n)

7) ab-ac+yb-yc=a(b-c)+y(b-c)=(a+y)(b-c)

8) ab+ac+xb+c=b(a+x)+c(a+1)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
