What is the value of x?
Dafna1 [17]

Answer:

28


Step-by-step explanation:

We use the concept of similarity to find the value of X.

Δ APR ≡  ΔCDR

∴ AR/CR = PR/DR

   (10+x)/x = (15+42)/42

42(10+x) = 57x

420 + 42x = 57x

57x - 42x = 420

15x = 420

x = 420/15

  = 28

: Which expression represents the factorization of 56st – 21t?
Luda [366]

Answer:

B: 7t(8s - 3)

Step-by-step explanation:

Method 1: check by expanding each of them

A: 7(8st - 3t)=56st-21t

B: 7t(8s - 3)=56st-2t

C: 3t ( 18s - 7)=54st-21t

D: 7s ( 8t - 3t)=56st-21st

Method 2: the common factors of 56st and 21t is: 7t

56st/7t=8s

-21t/7t=-3

56st-21t=7t(8s-3)
