Find the solutions to the equation below check all that apply 9x^2+9x-4=0 a. x=1/3 b. x=-4/3 c. x=-1/3 d. x=1/2 e. x=4 f. x=-2

A. x=1/3

B. x=-4/3

Solve for x over the real numbers: using the factor method:

9 x^2 + 9 x - 4 = 0

The left hand side factors into a product with two terms:

(3 x - 1) (3 x + 4) = 0

Split into two equations:

3 x - 1 = 0 or 3 x + 4 = 0

Add 1 to both sides:

3 x = 1 or 3 x + 4 = 0

Divide both sides by 3:

x = 1/3 or 3 x + 4 = 0

Subtract 4 from both sides:

x = 1/3 or 3 x = -4

Divide both sides by 3:

 x = 1/3 or x = -4/3

i believe the answer is d.

hope it you! : d

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
