Answer:
d=24g-6c
Step-by-step explanation:
12c+2d=48g
2d=48g-12c
d=24g-6c
It looks like angle FPG = twice angle FHG - which makes sense looking at it now, but I came up with the answer another way - see attached
first step to remove brackets
here write them in serial order,
=5x²+3x+4+5x²+5x-1
=5x²+5x²+3x+5x+4-1
=10x²+8x-3
Do 5x + 1 instead of 5x + 20, because there was more than likely a mistype.
Now we are also looking for the reciprocal so we do (5x + 1)/20
Either that is the answer or there is something missing. If this is not the answer then there needs to be a number we can set the equation equal to
