Answer:
40 minutes (I think)
Step-by-step explanation:
Calculate the time into minutes
15mph-0.25mpm
18mph-0.3mpm
add them together to find out how far they go combined each minute
0.55
divide 22 by 0.55 to find the total time
40 minutes
-4 + 2x + 8
-4 + 8 + 2x

Answer:
x = 12√2
Step-by-step explanation:
if its a square, all sides similar of 12 units.
then the bottom and side length is 12 units
we need to find x, the diagonal.
formula: a²+b² =c²
: 12² + 12² = c²
: c = √144+144
: c = √288
: c = 12√2
Therefore diagonal, x is 12√2
