Substitute 3 for wherever m is. Answer is 4
Answer:
(x - 8x)²
(x - 8x) (x - 8x).
using the identity
( a - b) ² = a² + b² - 2ab
a = x
b = 8x
x² + 64x - 16x²
Answer: OPTION A
Step-by-step explanation:
Apply the formula for calculate the distance between two points to know the value of the diameter of the circle:
The equation of the circle is standard form is:
Where r is the radius and (h,k) is the point of the center of the circle.
As we know the diameter, we can find the radius:
Substitute it into the equation:
Then, the answer is:
Answer:Answer: 26 ft.
Step-by-step explanation:
Answer:
207 m²
Step-by-step explanation:
width = x
length = 3x - 4
2(length + width ) = Perimeter
2(3x - 4 + x) = 64
4x - 4 = 64/2
4x - 4 = 32
4x = 32 + 4
4x = 36
x = 9 m - width
length = 3x - 4 = 3 · 9 - 4 = 23 m
Area = length · width = 23 · 9 = 207 m²
