Answer:
3x^2+15x-1=0
Step-by-step explanation:
4/(3x+15)=4x
4=12x^2+60x
12x^2+60x-4=0
3x^2+15x-1=0
Please solve after that, I cannot do everything for you
1) Let's solve for x, writing this equation.
3x +8*59 =0
3x +472=0 <em>Subtract 472 from both sides</em>
3x = -472
x= -472/3 or -157.33
2) So the answer is x= -472/3
Answer:
31 animals
Step-by-step explanation:
1 rabbit + 6 elephants + 6*2=12monkeys + 12 parrots = 31 animals
180-96= 84
That means 8x+12=84
84-12=72
That means 8x=72
72÷8=9
therefore X=9
