It’s A. The first option. Also pls brainlist

No real solutions, because for all real numbers the square of number is greater or equal 0.
16 + 4x = 10 + 14
16 + 4x = 24.
4x = 24 - 16
4x = 8
x = 8 ÷ 4
x = 2
8x = 2 × 8
8x = 16
Final answer = 16.
first of all you add all of the ratios together so it would be 1+3+5
That equals 9 then divide 72 by 9 which gets you 8. Then you times 8 by all of the ratios to get the answer
8:24:40
9x +1= 0
9x/9 +1-1=0
X= 9-1
X= 8
