Pls help 4 pointz
the question is below

Step-by-step explanation:

Simplifying

4x2 + -20 = 556

Reorder the terms:

-20 + 4x2 = 556

Solving

-20 + 4x2 = 556

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '20' to each side of the equation.

-20 + 20 + 4x2 = 556 + 20

Combine like terms: -20 + 20 = 0

0 + 4x2 = 556 + 20

4x2 = 556 + 20

Combine like terms: 556 + 20 = 576

4x2 = 576

Divide each side by '4'.

x2 = 144

Simplifying

x2 = 144

Take the square root of each side:

x = {-12, 12}

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

the correct answer is the second option
