Answer:
15y^2 - 21y
Step-by-step explanation:
A = LW
A = (5y - 7)(3y)
A = 15y^2 - 21y
Finding the radius from it's surface area, the volume of the sphere is of 268.08 cm³.
<h3>What are the surface area and the volume of an sphere?</h3>
For an sphere of radius r, we have that the surface area is given by:

The volume is given by:

Considering the surface area of 200.96 cm², the radius is given by:



r = 4 cm
Hence the volume is given by:

Answer: 267 x 67 is 17,889
Step-by-step explanation: its right
Step-by-step explanation:
x² + 12x = -35
x² + 12x + 35 = 0
(x + 5) (x + 7) = 0
x = -5 or -7
