Answer:

  x = 10

Step-by-step explanation:

Use the Pythagorean theorem. The sum of the square of the sides is the square of the hypotenuse.

  x² +(√200)² = (√300)²

  x² = 300 -200

  x = √100 = 10

The length of the unknown side is 10 units.

The area of a rhombus can be evaluated using the formula 1/2 d1d2 , where d1 represents the measure of one of its diagonals and
Eddi Din [679]

Answer:

Area of the rhombus will be a repeating decimal.

Step-by-step explanation:

In a terminating decimals, numbers get terminated after decimal like

1/4 = 0.25

while in repeating decimals, numbers get repeated after decimal like

1/3 = 0.33333

When we multiply two decimals which are repeating and terminating decimals the result will be a repeating decimal.

Therefore area of the rhombus will be a repeating decimal.

Find soluton to x^2-14x+49=25
Artyom0805 [142]

\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}
