If 1cm = 1mL then it would be 7mL that the whole bowl contains.
Regroup:
(x^4+2x^2-8)-(x^3+4x)=0
Factor: (x^2-2)(x^2+4)-x(x^2+4)=0
both terms have (x^2+4), so (x^2+4)(X^2-x-2)=0
factor again: (x^2+4)(x+1)(x-2)=0
x=1, x=2, x=2i, or x=-2i
-15/2 is the answer, Hope this helps;)
Hi there! To start with this situation, you are going to want to first divide 245 and 5 so you can find out how many miles this woman drives in 1 hour. We do that and get 49. Now is the easy part. Multiply 49 and 7. She will drive 343 miles in 7 hours.
