Answer:
Step-by-step explanation:
We are given the following in the question:
Height of plant = 20 inches
Growth of plant for next 4 week = 2h inches.
Growth of plant each week after 4 weeks = 2 inches.
Thus, the expression for plant height is given by
We have to find the expression for plant's height in 6 weeks.
Putting w = 6, we get,
is the required expression.
Answer:
4x + 12x = 320
16x = 320
x = 20
Step-by-step explanation:
This is because the diagram shows 4x + 12x and the total being, 320.
4x + 12x = 16x
and 320/16 = 20
so x = 20
hope this helped :)
If v = 15 km/h We have:
d1 = 30 km
d2 = 17 km
Since speed = distance/time follows time = distance/speed.
The total time of the entire trip is is the sum of the time of the first 30 km and the time of the remaining 17 km:
d1/v + d2/(v + 2) = 30/15 + 17/(15 + 2) = 2 + 1 = 3 hours
The answer is t=3hours
(-9)•(-9)•(-9)•(-9)= 6,561
0.3 is the answer, hope this help you out! :D
