\boxed{x=12 \ and \ x=2}

<h2>Explanation:</h2>

In this exercise, we have the following equation:

x^2-14x+49=25

We can write this Quadratic Equation in Standard Form as follows:

x^2-14x+49=25 \\ \\ Subtract \ 25 \ from \ both \ sides: \\ \\ x^2-14x+49-25=25-25 \\ \\ x^2-14x+24=0 \\ \\

So this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:

  • The sum is -14
  • The product is 24

Those numbers are:

  • -12 and -2
  • SUM: -12-2 = -14
  • PRODUCT: (-12)(-2)=24

So we can write this as:

x^2 + (a + b)x + ab=(x + a)(x + b) \\ \\ a=-12 \\ b=-2 \\ \\  x^2-14x+24=(x-12)(x-2)=0 \\ \\ So \ the \ solutions \ are: \\ \\ \boxed{x=12 \ and \ x=2}

allsm [11]

Answer:

<em>Final velocity, v = 21.75 m/s</em>

Step-by-step explanation:

Given that the relation between final velocity, initial velocity, acceleration and distance traveled is expressed as:

v^2=u^2+2as

Also, given that:

Initial velocity, u = 9 m/s

Acceleration, a = 7 m/s^2

Distance, s = 28 m

To find:

Final velocity, v = ?

Solution:

The given relation between v, u, a and s is:

v^2=u^2+2as

We have the values of initial velocity, acceleration and distance traveled in the question statement. We just need to put all these values to find the value of final velocity.

Let us put all the values in the given equation and try to find final velocity, v:

v^2=9^2+2\times 7 \times 28\\\Rightarrow v^2=81+14 \times 28\\\Rightarrow v^2=81+392\\\Rightarrow v^2=473\\\Rightarrow v=\sqrt{473}\\\Rightarrow v=21.75\ m/s

So, the answer is:

<em>final velocity, v = 21.75 m/s</em>

Which events are dependent? Choose all that apply.
Viefleur [7K]
The first three are dependent variables as the outcomes could potentially change due to any of these circumstances.
The last one is an independent variable due to the fact that rolling a die several times will not affect the next outcome.

Answer:

249.6

Step-by-step explanation

There are 4 identical equilateral triangle,

we can find the area of one and multiply by 4

area of triangle = \frac{1}{2} *base*hight=\frac{1}{2}*12*10.4=62.4

now 62.4*4 = 249.6
