The equivalent expression of (\sqrt x - 2)(\sqrt x + 9) is x + 7\sqrt x - 18

<h3>How to determine the equivalent equation?</h3>

The expression is given as:

(\sqrt x - 2)(\sqrt x + 9)

Expand the expression

x - 2\sqrt x + 9\sqrt x - 18

Evaluate the like terms

x + 7\sqrt x - 18

Hence, the equivalent expression of (\sqrt x - 2)(\sqrt x + 9) is x + 7\sqrt x - 18

Answer:

Missing side = x+2

Step-by-step explanation:

The perimeter of the classroom, 6x+3, is equal to the 4 side lengths added up.

In their first line of work, the first plus sign should be an equal sign as follows:

6x+3 = 3x+1+x+x+?

simplify

6x+3 = 5x+1+?

subtract (5x+1) from both sides

x+2 = ?

There's the length of the missing side.

Find the area. The figure is not drawn to scale.
Rina8888 [55]
Answer:
area = 13.8 cm²

Explanation:
The area of the triangle can be calculated using the following rule:
area of triangle = (1/2) * base * height

In the given:
base of triangle = 6.9 cm
height of triangle = 4 cm

Substitute with the givens in the above equation to get the area as follows:
Area = (1/2) * (6.9) * (4)
Area = 13.8 cm²

Hope this helps :)

Let f(x) = 4x - 5 and g(x) = 6x - 3. Find f(x) - g(x).
professor190 [17]
F(X) = 4x - 5
G(X) = 6x - 3

F(x) - G(x)

(4x - 5) - (6x - 3)

4x - 5 - 6x + 3

-2x - 2

-2(X + 1).

I believe this would be the simplified solution.

Zinaida [17]

Answer:

The probability of of a randomly chosen student being exactly 21 years old.

= 1.293

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given Population  size n = 500</em>

<em>Mean of the Population = 20 years and 6 months</em>

<em>                                        = </em>20 + \frac{6}{12} = 20 +0.5 = 20.5 years<em></em>

<em>Standard deviation of the Population = 2 years</em>

Let 'X' be the range of ages of the students on campus follows a normal distribution

Let   x =21

            Z = \frac{x-mean}{S.D}

            Z = \frac{x-mean}{S.D} = \frac{21-20.6}{2} =0.2

<em>The probability of a randomly chosen student being exactly 21 years old.</em>

<em>P( Z≤21) =  0.5 + A( 0.2) </em>

            = 0.5 +0.793

           =  1.293
