Hello,
3x²-26x+16=3x²-24x-2x+16=3x(x-8)-2(x-8)=(x-8)(3x-2)
Perimeter= 2*(x-8+3x-2)=2*(4x-10)=8x-20
You would multiply 62 1/4 and 4. Which you cant do that so you would have to make it into a inproper fraction so that will be 249/4 times 4/1 then you can multiply which your answer would be 996 /4 and then in simplest form would be 249/1= 249
84+63i would be the complex conjugate of84-63i
