Answer:
A. 16 - 4 x = 4(4 - x)
B. 4 x + 8 = 4( x + 2)
C. -8 b - 24 = -8(b + 3)
D. 54 + 9 x = 9 (x + 6)
Step-by-step explanation:
Here, the given expressions are:
A. 16 - 4 x
Now, 16 and 4 have 4 as their COMMON FACTOR.
⇒Taking out 4 as the factor, we get: 16 - 4 x = 4 ( 4 - x)
Hence, the equivalent expression of 16 - 4 x = 4 ( 4 - x)
B. 4x + 8
Now, 4 and 8 have 4 as their COMMON FACTOR.
⇒Taking out 4 as the factor, we get: 4 x + 8 = 4 ( x + 2)
Hence, the equivalent expression of 4 x + 8 = 4 ( x + 2)
C. -8b - 24
Now, -8 and -24 have (-8) as their COMMON FACTOR.
⇒Taking out (-8) as the factor, we get: -8b - 24 = (-8) ( b+ 3)
Hence, the equivalent expression of -8b - 24 = (-8) ( b+ 3)
D. 54 + 9x
Now, 54 and 9 have (9) as their COMMON FACTOR.
⇒Taking out (9) as the factor, we get: 54 + 9 x = 9( 6 + x)
Hence, the equivalent expression of 54 + 9 x = 9( 6 + x)
