Answer:

The correct answer is option B. 8,16, 20

Step-by-step explanation:

Its given that,ΔJKL ~ ΔPQR, with a scale factor of 3 : 4

The sides of ΔJKL are, 6,12,15

Let 'x', 'y', and 'z' be the sides of ΔPQR

We know that if two triangles are similar, then the ratio of corresponding sides are in same raio.

To find x

6/x = 3/4

x = 8

To find y

12/y = 3/4

y = 16

To find z

15/z = 3/4

z = 20

Therefore the sides of ΔPQR are 8,16 and 20

Option B. 8,16,20 is the correct answer

The school gym can hold 650 people. A permanent bleacher in the gymn holds 136 people. The event organizers are setting up 25 ro

igomit [66]

650 -136=514
514 divided by 25 = 20.56
So it would be 21
This will give you a little extra chairs but they have to be equal in each row

What is the slope and y intercept of y=-7x+12

MrRissso [65]

Hi there!

So the format of slope-intercept form is:

y= mx+b

m= your slope
x = just a variable
b= your y- intercept

Using those hints, see if you can figure out the answer! :)

Hope this helped!
