A(b+c)=ab+ac

distribute

20(c+2.75)=20(c)+20(2.75)=20c+55

20c+55=124.80
minus 55 from both sides
20c=69.8

divide both sides by 20
c=3.49

-2 (3x - 4)= -6x - 8 true or false
Mazyrski [523]
<span>False.
-2(3x - 4) distributes to become -6x + 8
Thus, it is easy to tell it is false:

-2(3x - 4)= -6x - 8
-6x + 8 = -6x - 8
Add 6x to both sides;
8 </span>≠<span> -8</span>

Luda [366]

Answer:  B, A, B

<u>Step-by-step explanation:</u>

Let's find the z-score for both companies using the formula: z=\dfrac{x-\mu}{\sigma}

Company A: z=\dfrac{43-38.2}{1.7}=\large\boxed{2.8}

Company B: z=\dfrac{43-36.9}{2.4}=\large\boxed{2.5}

The z-score from Company B is closer to 0 than the z-score of Company A so it it more likely that a package of 43 lozenges is produced by Company B

Galina-37 [17]

Answer:

No, it is not prime.

Step-by-step explanation:

67^2 = 4489

A number cannot be prime if it is divisible by a number besides 1 and itself. 4489 is divisible by 67; no perfect square can be prime.
