Answer:
n = 11
Step-by-step explanation:
n + 1 = 4 (n - 8)
n + 1 = 4n - 32
n - 4n = - 32 - 1
- 3n = - 33
- n = - 33/3
- n = - 11
n = 11
Can you fix this problem first so I can do it for you?
Answer:
The answer is below
Step-by-step explanation:
From the image attached we can see that the width of the garden is 6 ft. The length of the garden is the slanting side of the triangle (hypotenuse).
Let x be the length of the garden. The height of the triangle = 40 ft - 15 ft = 25 ft.
The base of the triangle = 80 ft - 75 ft = 5 ft.
The length of the garden is gotten using Pythagoras:
x² = 25² + 5²
x² = 650
x = 25.5 ft.
The area of the garden = length * width = 25.5 * 6 = 153 ft²
Hence the approximate area = 160 ft²
You are multiplying by 3 each time. This sequence is geometric.
9 = 3*3 = 3^2
27 = 3*9 = 3*3*3 = 3^3
81 = 3*27 = 3*3*3*3 = 3^4
and so on.
The general rule is 3^x which is choice D
3 1/2 ft = 3.5 ft
1 ft = 12 inches
3.5 ft = 3.5 * 1 ft = 3.5 * 12 inches = 42 inches
3 1/2 ft = 42 inches
All boxes must measure less tan 42 inches.
Only choice C has three measurements that are less than 42 inches.
Answer: C.
