LCM of 15 & 6 = 30
then take the highest exponent for each variable
answer is:
30x^4y^8z^9
It should be x-2y because you have tooooooooooooooooooooooooo
Answer:
gradient m = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = - x - 3 ← is in slope- intercept form
with gradient m = - 1
Answer: 7 people need 16 minutes to paint 4 walls.
Step-by-step explanation:
Since we have given that it takes 63 minutes to paint 9 walls ,
So, we will apply "time and work formula" i.e.

where,
H denotes number of hours or minutes,
D denotes number of days
M denotes number of men
W denotes work done them,
So, we need to calculate number of minutes for 7 people to paint 4 walls,

So, 7 people need 16 minutes to paint 4 walls.
You could do either for the length 4 and the width 8 it would be 32 or you could do 32 and 1
