Solve for x. Write both solutions, separated by a<br> comma.<br> 9x^2+ 3x – 2 = 0

Answer:

x=1/3, x=-2/3

Step-by-step explanation:

9x^2 +6x -3x -2=0

6x and -3x add up to 3x. You need four terms to factor.

Then you factor=

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

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

Then you can make two equations

3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.

3x-1=0

3x=1

x=1/3

3x+2=0

3x=-2

x=-2/3

So your answers are x=1/3, x=-2/3

hope this helps!

I really need help with this Triangle problem.

dedylja [7]

Answer:

12

Step-by-step explanation:

Here we use SOHCAHTOA

Seeing as we have the hypotenuse and we are working to find out the opposite, we use SOH

Sin(x)= Opposite/Hypotenuse

Sin(45) = x/ $12\sqrt{2} \\$

×12 root 2

sin(45) times 12 root 2= 12

x=12

Answer:

So in scientific form 4000 miles will be equal to $4\times 10^3miles$

Step-by-step explanation:

We have given that radius of earth is 4000 miles

4000 miles can be written as 4×1000

We have to written 4000 miles in scientific form

We know that 1000 can be written in scientific form as $1000=10^3$

So $4000miles =4\times 1000=4\times 10^3miles$

So in scientific form 4000 miles will be equal to $4\times 10^3miles$
