Step-by-step explanation:

x {}^{2}  + 3x - 18 \\  = x {}^{2}  + (6 - 3)x - 18 \\  = x {}^{2}  + 6x - 3x - 18 \\  = x(x + 6) - 3(x + 6) \\  = (x + 6)(x - 3)

What is the area of triangle rst? 6 square units 9 square units 12 square units 18 square units
Butoxors [25]

The area of the considered triangle RST is given by: Option A: 9 sq. units.

<h3>How to find the area of a triangle?</h3>

If we have:

  • Length of its base = b units
  • Its height = h units long,

Then we get:

Area of a triangle = \dfrac{b \times h}{2} \: \rm unit^2

The missing image is attached below.

If we take the base of the triangle as RS, then as the line UT is perpendicular to RS (as RS is parallel to x axis and UT is parallel to y axis) and touching from the base line RS to T, thus, it can be taken as height.

Thus, we have:

Area of RST = half of length of RS (base) times length of UT (height)

As visible from image, we have:

Length of RS = 6 blocks of unit length = 6 units

Similarly, length of UT = 3 units

Thus, we get:

Area of RST = \dfrac{6 \times 3}{2} = 9 \: \rm unit^2

Thus, the area of the considered triangle RST is given by: Option A: 9 sq. units.

If winchester weighs 100 kilograms (220 pounds) and is 2 meters tall (6 feet 5 inches), his bmi would be
Rasek [7]
By definition, the body mass index (bmi) is given by:
 bmi =   \frac{weight}{height ^ 2} &#10;
 Substituting values:
 bmi =  \frac{100}{2^2}&#10;
 Rewriting we have:
 bmi = \frac{100}{4}
 Making the corresponding calculations we have:
 bmi = 25&#10;
 Answer:
 
The body mass index for winchester is given by:
 
bmi = 25
