Answer:
560 hamsters
Step-by-step explanation:
==> 50 + 40% = 70
==> multiply 70 by 8 years
==> 70 × 8
==> 560
X=4
After squaring both sides, you get
4(x+5)=x^2-20x+100
Multiply
4x+20=x^2-20x+100
Collect like terms
4x+20-x^2+20x-100=0
Reorder
24x-80-x^2=0
Change signs & Write as difference. You end up with
x^2-4x-20x+80=0
Factor
x-4=0 , x-20=0
4=4 , 0=20
x=4
