I would say 3amp I’m not sure
Simplify the following:
6 a b - 3 x + 2 a b
Grouping like terms, 6 a b - 3 x + 2 a b = -3 x + (6 a b + 2 a b):
-3 x + (6 a b + 2 a b)
a b 6 + a b 2 = 8 a b:
Answer: -3 x + 8 a b
2(444x+3a+44c) I think so
Answer:

Step-by-step explanation:
Given

The sample mean
This is calculated using:

So, we have:



Answer:
130°
Step-by-step explanation:
∠BXF = ∠BXA + ∠AXF = 90° +40°= 130°
see ∠AXF =∠CXD opposite angles
∠CXD = 90° given
∠BXA = 40° given
