What is the value of the expression

Arturiano [62]

Answer:

OA) 14

Step-by-step explanation:

2((7+1)-1)

2(8-1)

You could expand the brackets then simplify or just simplify now. It will be better to simplify now though but I will do both methods.

Simplifying first:

2(7) = 2 × 7 = 14

Our answer is 14 So answer is OA) 14

Expanding first then simplifying:

2(8-1) = 16-2 = 14

Our answer is 14 So answer is OA) 14

Answer:

$Volume = 24\ ft^3$

Step-by-step explanation:

Given [Missing from the question]

$Length = 170cm\\ Width = 100cm\\ Height = 40cm$

Required

Determine the volume

This is calculated as:

$Volume = Length * Width * Height$

$Volume = 170cm * 100cm * 40cm$

$Volume = 680000cm^3$

Convert to cubic foot [Divide by 28317 ]

$Volume = \frac{680000\ ft/^3}{28317}$

$Volume = 24.0138432744\ ft^3$

$Volume = 24\ ft^3$ --- approximated
