Solve 3x^2+4=436
Please solve step by step

12

Step-by-step explanation:

Your goal with variables should always be to isolate them.

so the first step is to subtract the 4

3x^2+4=436

       -4= -4

3x^2=432

The next step to isolate the variable x is to get rid of the 3. To get rid of the 3 you have to divide both sides by 3 since it is the opposite of multiplying.

3x^2=432

/3.    =/3

x^2=144

the last step to isolate the x is to do the opposite of what an exponent is, which is to find the square root. So when you square the x^2, the exponent cancels out.

square root of x^2=x

square root of 144=12

x=12

hope this helps!

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
