Answer:
Expression 8 • 24 represents the total area.
Option A is correct.
Step-by-step explanation:
Width of living room = 8 ft
Length of living room = 24 ft
We need to calculate area:
The formula used is: 
Putting values to get the expression

So, Expression 8 • 24 represents the total area.
Option A is correct.
Part A
25-9=16
16/2=
8
The length of the rope holding the top right corner of the banner to the post is
8 feet long
Part B
13-9-2=
2 for width
25-8=16 16/2=
8 for length
Use the Pythagorean Theorem

+

=


64+4=

68=


34=c
The length of the rope from the bottom right corner of the banner to the post is
34 feet

Answer:
D The solution is 35, which represents the number of miles she runs each week.
Step-by-step explanation:
Given that Gisele trains 7 days a week, the total of miles she cycles and runs in a week can be divided by 7, or multiplied by 1/7 to find her daily average. Her total number of miles ran for the week combined with her cycling miles multiplied by 1/7 would average 20 miles daily. Since the run is the same each day, using the equation:
1/7(105 + r) = 20 will give the value of 'r' in the number of miles ran per week
105 + r = 140 (multiply both sides by '7')
r = 35 (subtract '105' from both sides)
