Answer:

x = -1/2 and x = -3

Step-by-step explanation:

2x² + 7x + 3 = 0

Using AC method:

2 × 3 = 6

Factors of 6 that add up to 7: 1 and 6

Divide by 2 and reduce: 1/2, 6/2 = 3/1

The factors are (2x + 1) and (x + 3)

(2x + 1) (x + 3) = 0

2x + 1 = 0

x = -1/2

x + 3 = 0

x = -3

The solutions are x = -1/2 and x = -3.

The volume of a cone with a height of 6 cm is 8 PI cubic centimeters. Which expression can be used to find r, the radius of the

timama [110]

Answer:

The correct option is D.

8π = 1/3 * π * (r)² * 6

Step-by-step explanation:

First of all to solve this problem we have to know the formula to calculate the volume of a cone

v = volume = 8π

r = radius

h = height = 6cm

π = pi

v = 1/3 * π * r² * h

we replace with the known values

8π = 1/3 * π * (r)² * 6

If we look at the options, the correct option is D.
