Answer:

1

Step-by-step explanation:

A number raised to the 3rd power is equal to that number multiplied by itself twice. Below I have expanded the expression to visualize this process. If this makes it more confusing, the main way is just to go from line 1 to line 4.

9 + (-2)³                          <---- Original expression

9 + (-2 x -2 x -2)             <---- (-2)³ expanded

9 + (4 x -2)                     <---- -2 times -2

9 + (-8)                           <---- 4 x -2                    

1                                     <---- 9 - 8

V = lbh ( l is length, b is breadth and h is height ), that is

V = 14 × 8 × 5 = 560 cm³

number of bricks made = \frac{16800}{560} = 30

2 3/4 x 8 = blank/4 x 8/1
Alex

Answer: 11

Step-by-step explanation:

2 3/4 × 8 = p/4 × 8/1

Let p be the missing number

Convert the mixed fraction 2 3/4 to proper fraction, multiply 4 x 2, then add 3= 11/4

11/4 × 8 = p/4 ×8

p= 11

I hope this helps.
