Desperate, triangle abc and triangle pqr are similar. triangle abc is dilated by a scale factor of 1.25 and rotated 45 degrees counterclockwise about point b to form triangle pqr. the side lengths of triangle abc are line ab, 5 units; line bc 4.2 units; and line ac 4 units. match each side of triangle pqr to its length. choices 5.25 units, 5 units, 6.25 units match which side pq, qr, and pr

QR=5.25 units

PR=5 units

PQ=6.25 units

Step-by-step explanation:

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
