help me i need this done in 20 minutes

2b + -6

Step-by-step explanation: To simplify, we will use the distributive property.

Before distributing, I would change the -3 to plus a negative 3.

So we have 2(b + -3).

Now, distributing the 2 through the parenthses, we have 2(b) + 2(-3).

2(b) is 2b and 2(-3) is -6.

So we have 2b + -6 as our final answer.

2b - 6

Step-by-step explanation:

2(b-3)=

Distribute

2*b - 2*3

2b - 6

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
