Answer:
the guinea pig is 21 cm longer
Step-by-step explanation:
fish = 40 mm
guinea pig 25 cm
convert the fish to cm
1 cm = 10 mm
40 mm * 1 cm/10 mm = 4 cm
guinea pig - fish
25 cm - 4 cm
21 cm
the guinea pig is 21 cm longer
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
Yes because removing the common factor is important. There are a few steps, then you can factor by regrouping. Hope this helps.
