Area of the warehouse $=60,000$ ft^2$

Let the length of the warehouse=l

The warehouse's width is exactly $\dfrac23$ of its length

Therefore: Width of the warehouse $=\dfrac23l$

Area =Length X Width

Therefore:

$\dfrac23l*l=60000\\$Cross multiply\\2l^2=60000*3\\2l^2=180000\\$Divide both sides by 2\\2l^2 \div 2=180000 \div 2\\l^2=90000\\l^2=300^2\\$Length, l=300 feet\\Recall: Width =\dfrac23l\\$Therefore, Width of the warehouse=\dfrac23*300=200$ feet$

kipiarov [429]

Answer:

1. Commutative Property of Addition

2. Distributive property

Step-by-step explanation:

Given

$Line 1: 4(8+9x)$

$Line 2: 4(9x+8)$

$Line 3: 36x+32$

Required

Justify each step

From Line 1 to 2:

The property from Line 1 to 2 depicts $a + b = b + a$ ;

i.e.

$4(8 + 9x) = 4(9x + 8)$

This is referred to as Commutative Property of Addition

From Line 2 to 3:

The property here depicts $a(b + c) = a * b + b * c$

i.e.

$4(9x + 8) = 4 * 9x + 4 * 8$

$4(9x + 8) = 36x + 32$

This is referred to as Distributive property
