1 cm= 10 mm
7 cm= 70mm
difference between grasshopper and cockroach= 99mm - 70mm
= 29mm
Answer:
The answer is option 1.
Step-by-step explanation:
Axis of symmetry means the middle x-coordinates of the parabola. So in order to find the x value, you have to find the TP which is Turning Point by using Completing the Square :

Let y = 0,







Next, you have to solve the x value :
x + 3 = 0
x = -3
30 * x = 245
lets divide 30 and 245, 245 / 30 = 8.167
8.167 x 30 = 245
