Answer:
what is that ............
L = 16.51
Get variable onto one side of equation and simplify:
(−7.4 )+ L = 9.11
L = 9.11 + 7.4
L = 16.51
Answer:
3(3b +4)
Step-by-step explanation:
The greatest common factor (GCF) of 9 and 12 is 3, so you're being asked to factor that out.
9b +12 = 3(3b +4)
_____
The GCF can be found a couple of ways. One of them is to list the prime factors and identify those that are common.
9b = 3 × 3 × b
12 = 2 × 2 × 3
For these two terms, the only common factor is 3.
