Divide by 21 to put the equation in intercept form.
x/(21/9) + y/(-21/7) = 1
x/(7/3) + y/(-3) = 1
The x-intercept is (7/3, 0)
The y-intercept is (0, -3)
The 3rd choice is appropriate.
BC = 18
AB = AC, hence
8x - 4 = 5x + 11 ( subtract 5x from both sides )
3x - 4 = 11 ( add 4 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
BC = 4x - 2 = (4 × 5 ) - 2 = 20 - 2 = 18
Answer:
Cylinder, A = 2π • w • h + 2π • w to the second power square units
Step-by-step explanation:
A right circular hollow cylinder is a 3D region enclosed by two right circular cylinders having the same axis and two parallel annular bases perpendicular to the cylinders' common axis which will be formed when you rotate the given by 360 degrees.
