for 10 x = 28.
8x-44=180
+44. +44
8x=224
224/8=28
the answer is 0.25
I got this out of mt textbook not to long ago
hope this helped
Answer:
V = 24pi
or 75.36 ( using 3.14 for pi)
or 75.39822369 ( using the pi button)
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius and the height
V = pi (2)^2 * 6
V = pi 4*6
V = 24 pi
If we approximate pi by 3.14
V = 3.14 * 24 = 75.36
If we use the pi button
V =75.39822369
Step-by-step explanation:
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42
