Answer:
Step-by-step explanation:
8x² + 2(x²-1) = 8x² + 2*x² - 2*1
= 8x² + 2x² -2
= 10x² -2
Like terms: 8x² , 2x²
Answer:
1884 flowers
Step-by-step explanation:
Radius of the garden=150 ft
To determine the number of flowers needed to surround the circular garden, we first find the perimeter.

Since the flowers are spaced every 6 in, we need to convert from inch to feet because we cannot divide different units.
Now, 12 Inch =1 Feet
Therefore, 6 Inch =0.5 feet
To determine the number of flowers, we simply divide the perimeter by 0.5 ft.
Number of flowers=942/0.5
=1884 flowers
Answer: 49
Step-by-step explanation:
There would be 49 dots because each number is a square number. You skip 1 so every square‘s number is one less than the square root of the number of dots.
hope this helps
We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.
