The triangles shown are similar. Which similarity statement expresses the relationship between the two triangles?

Pani-rosa [81]

Answer:

The similarity statement that expresses the relationship with the two triangles is that "Triangle P Q R is similar to Triangle W X Y"

Step-by-step explanation:

In drawing and labeling triangles, the three angles are labeled with letters that follow alphabetically. Thus, a triangle A B C should be in similarity with triangle x y z. Like wise from the above statements, triangle P R Q can only be similar in labeling in the range of W X Y even if the figures are not shown.

Solve for x: 2(3x - 9) = 18x x = -3/2 x = 3/2 x = 0 x = 6

Mila [183]

Remember yo can do anything to an equation as long as you do it to both sides

so
remember distributive property
a(b+c)=ab+ac

so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x

easier way is to first divide both sides by 2

x=-3/2

Select the correct answer from each drop-down menu. Complete the statements about these similar pyramids. Two square pyramids A

Scrat [10]

The ratio of the heights of these pyramids is 3 : 1, the ratio of the base areas is 9 : 1 and the ratio of the volumes is 27 : 1.

<h3>What is ratio?</h3>

Ratio can be defined as a mathematical expression which denotes the proportion of two (2) or more physical quantities to one another and the total quantities.

The ratio of the heights of these pyramids is given by:

Ratio = Height of pyramid A : Height of pyramid B

Ratio = (3V/lw) : (V/lw)

Ratio = 3 : 1.

The ratio of the base areas of these pyramids is given by:

Ratio = Base area of pyramid A : Base area of pyramid B

Ratio = (3a)² : a²

Ratio = 9a : a

Ratio = 9 : 1.

The ratio of the volumes of these pyramids is given by:

Ratio = Volume of pyramid A : Volume of pyramid B

Ratio = (3l × 3w × 3h)/3 : (l × w × h)/3

Ratio = 27 : 1.
