Hello,
Answer A
(3x-4)²-(x+7+x²+2)=9x²-24x+16-x-x²-9
=8x²-25x+7
3\4a=24 multiply both sides by 4 to get rid of 4(4 x 24=96)
3a=96 divide both sides by 3 to remain with a
a=32
The answer is x=3
because 3x2 is 6 and 6x6 is 36 because a hexagon has 6 sides, and 3x3 is 9+3 is 12 and 12+12 is 24 and 3+3 is 6 so 6+6 is 12 and is you add that to 24 then that’s 36 aswell.
