**Answer:**

**C.47**

**Step-by-step explanation:**

You want to plug in all the numbers which gives you 3^3+2(8)- -4. You do 3*3*3 which gives you 27. You then do 2(8) which gives you 16. So your problem now is 27+16- -4. 27+16 is 43 and being you are subtracting a negative, it turns to a positive. So your answer ends up being **47**.

I am not sure on this one but I think it may be like 6 years. I will try to find a better answer ... I have not seen any question like this one ... I tryed to answer it on a sheet of paper but I cant seem to get it ... I am so sorry if I cant help ... <3

The length of the **actual pen** is **20 meters. **

The **scale drawing **is a reduced form of an original image. The **scale drawing **is reduced by constant dimensions. In this question, the **scale **is 5cm : 2m. This means that on the **scale drawing, **5cm represents 2m.

**Length **of the **actual pen **= (length of the pen on the scale drawing x 2m) / 5cm

(50 x 2) / 5

100 / 5

= **20 m**

**Answer:**

see explanation

**Step-by-step explanation:**

Given that U is the midpoint of TV, then

TU = UV , substitute values

8x + 11 = 12x - 1 ( subtract 12x from both sides )

- 4x + 11 = - 1 ( subtract 11 from both sides )

- 4x = - 12 ( divide both sides by - 4 )

x = 3

Thus

TU = 8(3) + 11 = 24 + 11 = 35

UV = 12(3) - 1 = 36 - 1 = 35
