38 seedlings
solve 2n + 2 = 78
subtract 2 from both sides
2n = 78 - 2 = 76
divide both sides by 2
n = 
= 38
number of seedlings that can be planted is 38
= <span>6x + 2(3x + 5) + (-9)
= 6x +6x + 10 - 9
= 12x + 1
In short, Your Final Answer would be 12x + 1

Answer:
h = 24 cm
Step-by-step explanation:
The formula for area of a triangle is
A = (1/2)bh where b is the base and h is the height.
We are told that the base is 5 times the height, this translates to
b = 5h, so we can rewrite our formula to
A = (1/2)(5h)(h) or
A = (1/2)5h²
We are given A = 1,440, so plug that in and solve for h...
1,440 = (1/2)5h²
2,880 = 5h² (multiply both sides by 2 to get rid of the fraction)
576 = h² (divide both sides by 5 to get the h value by itself)
24 = h (take the square root of both sides)
