Step-by-step explanation:
It's the <em>DISTRIBUTIVE PROPERTY</em>:
m(a + b) = ma + mb

Other properties:
Commutative Property:
<em>of addition: a + b = b + a</em>
<em>of multiplication: a · b = b · a</em>
Associative Property:
<em>of addition: (a + b) + c = a + (b + c)</em>
<em>of multiplication: (a · b) · c = a · (b · c)</em>
The area of the roof is 1984 sq. ft. 1984 square feet of roofing is needed for the roof of a building that is 32 ft wide and 62 ft long.
Given, the length of the roof is 62 ft long and the width of the roof is 32 ft wide. Therefore, the area of the roof is length * width.
Area of the roof = length of the roof * width of the roof
Area = 62 ft * 32 ft
Area = 1984 sq. ft
Here, also given the slope of the roof is 1:2 which indicates the ratio of rise and run.
Slope of the roof = Rise / Run = 1 / 2
Then, the slope factor is
=
= 0.04167

The right question is:
How many square feet of roofing is needed for the roof of a building that is 32 ft wide and 62 ft long?
Answer: it would take 280 miles before Laura pays the same amount for both plans..
Step-by-step explanation:
Let x represent the number of miles that Laura drives using either the first plan or the second plan
Let y represent the total cost of x miles when using the first plan
Let y represent the total cost of x miles when using the second plan
The first plan has an initial fee of $55.98 and costs an additional $0.13 per mile driven. This means that the total cost of x miles would be
y = 0.13x + 55.98
The second plan has an initial fee of $69.98 and costs an additional $0.08 per mile driven.This means that the total cost of x miles would be
z = 0.08x + 69.98
To determine the number of miles that Laura would drive before the amount for both plans becomes the same, we would equate y to z. It becomes
0.13x + 55.98 = 0.08x + 69.98
0.13x - 0.08x = 69.98 - 55.98
0.05x = 14
x = 280
