Answer:

2, -1/3

Step-by-step explanation:

3x^2 - 5x - 2 = 0

Find the factors of 3*-2 that are the same as the addends for -5:

3*-2 = -6

Factors of -6: -6*1

Addends: -6 + 1

3x^2 - 6x + x - 2 = 0

(3x^2 - 6x) + (x - 2) = 0

(factor in each parantheses)

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

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

(set each of the terms to 0 and solve)

3x + 1 = 0

3x = -1

x = -1/3

x - 2 = 0

x = 2

Hope it helps (●'◡'●)

a circular fountain has a radius of 9.4 feet. find its diameter and circumference to the nearest tenth.
pickupchik [31]

Radius = r

Diameter : D = r*2

Circumference : C = 2πr

π = 3.14 rounded

9.4*2 =18.8

2(3.14)9.4

6.28*9.4= 59.03200

Diameter = 18.8

Circumference = 59.03200

What is the true solution to 2 In 4x= 2 In 8?
Pachacha [2.7K]

Answer:

x=2

Step-by-step explanation:

2In(4x)=2In(8)

determine the defined range

2In(4x)=2In(8) , x is greather than 0

divide both sides by 2

In(4x)=In(8)

set the arguments equal

4x=8

divide both sides by 4

x=2, x is greater than 0

x=2
