5 0

For this case we have the following expression:

10-2x

Let's evaluate the expression for some values of x.

We have then:

For x = 1:

10-2 (1)\\10-2\\8

For x = 2:

10-2 (2)\\10-4\\6

For x = 3:

10-2 (3)\\10-6\\4

For x = 4:

10-2 (4)\\10-8\\2

For x = 5:

10-2 (5)\\10-10\\0\\

Answer:

The value of the expression in ordered pairs is:

  • (1,8)
  • (2.6)
  • (3,4)
  • (4.2)
  • (5.0)

In an isosceles trapezoid the length of a diagonal is 25 cm and the length of an altitude is 15 cm. Find the area of the trapezo
andreev551 [17]

Answer:

The area of the trapezoid is 525\ cm^{2}

Step-by-step explanation:

we know that

The area of a isosceles trapezoid is equal to the area of two isosceles right triangles plus the area of a rectangle

step 1

<em>Find the area of the  isosceles right triangle</em>

Remember that

In a isosceles right triangle the height is equal to the base of the triangle

we have

h=15\ cm

so

b=15\ cm

The area is equal to

A=\frac{1}{2}(b)(h)

substitute the values

A=\frac{1}{2}(15)(15)=112.5\ cm^{2}

step 2

Find the area of the rectangle

The area of the rectangle is equal to

A=LW

we have

W=15\ cm -----> is the height of the trapezoid

d=25\ cm  -----> the diagonal of the rectangle

Applying the Pythagoras Theorem

25^{2}=L^{2}+15^{2}\\L^{2}=25^{2}-15^{2} \\ L^{2} =400\\L=20\ cm

The area of the rectangle is

A=(20)(15)=300\ cm^{2}

step 3

Find the area of the trapezoid

A=2(112.5\ cm^{2})+300\ cm^{2}=525\ cm^{2}
