*please help me out if you know how to solve, last person I asked just put a random awnser for point, the problem is bellow and
kicyunya [14]

     For both of these, we will divide the wanted outcome by the number of possible outcomes. We will end up with a decimal. A decimal multiplied by 100 becomes a percent.

[a] 50%

\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed}}{\text{Period 2's class}} =\frac{12}{24} =0.5,\:0.5*100=50\%

[b] 52%

\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed from Period 3}}{\text{fails from both classes}} =\frac{13}{25} =0.52,

    \displaystyle 0.52*100=52\%

Factor the following
murzikaleks [220]
(x+2)^2

This can be rewritten as:

(x + 2)(x + 2)

Multiply everything in the second parenthesis by x.

x^2 + 2x

Multiply everything in the second parenthesis by 2.

2x + 4

Add these equations together.

x^2 + 2x + 2x + 4

Combine like terms.

x^2 + 4x + 4

Hope this helps!

(-1,4) and ( 1, -1) Find the distance between each pair of points
Nikolay [14]

Answer:

\sqrt{29}

Step-by-step explanation:

We are basically trying to find the hypotenuse of the triangle.

The distance between the x is 2, and the distance between the y is 5, which makes a length and a width.

Pythagrenum theorem: a^2+b^2=c^2

2^2 is 4, 5^2 is 25.

4+25 is 29.

The distance is \sqrt{29}.
