What does 10a + 4=?
Answer is :2 (5a + 2)
1.
Step 1: Flip the equation.
p=2w+21
Answer:
p=2w+21
2.
Step 1: Add -b to both sides.
Step 2: Divide both sides by 2.
Answer:
a=
−1
/2b+1/2 c
3.
Step 1: Add 2a to both sides.
−2a+b+2a=c+2a
b=2a+c
Answer:
b=2a+c
-3c^2+6c that is the answer
The simplified answer is 34560
The cluster's height above the valley floor can be modeled by the equation:

When the cluster seeds will reach the valley floor, the height of the cluster seeds above the valley floor will be 0. So substituting h(t) = 0 in the above equation we can find the time when the cluster seeds will reach the valley floor.

Since t represents the amount of time, it cannot have a negative value. So the only acceptable value of t is t=20
Thus it will take 20 seconds for the cluster of seeds to reach the valley floor. Thus the correct answer is option C
