Calculate the speed traveled for each situation below and then put them in
order from least to greatest.
Moving 12 km in 40
minutes
Moving 18 km in 30
minutes
Moving 6 km in 15 minutes
t, Moving 10 km in 20
minutes

Solution:

The speed is given by formula:

Moving 12 km in 40  minutes

Moving 18 km in 30  minutes

Moving 6 km in 15 minutes

Moving 10 km in 20  minutes

Put them in  order from least to greatest

Moving 12 km in 40  minutes = 0.3 km/min

Moving 6 km in 15 minutes = 0.4 km/min

Moving 10 km in 20  minutes = 0.5 km/min

Moving 18 km in 30  minutes = 0.6 km/min

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
