I'm not sure if this is exactly right because the wording of the problem is confusing.
Answer:
a) Number of square feet of wallpaper for bedroom = 12x^2 - 21
b) Number of square feet of wallpaper for living room = 14x^2 - 42
c) Total amount of wallpaper needed = 26x^2 - 63
d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.
Step-by-step explanation:
a) First find the area of each wall.
Length: 3x, Width: 3x, Height: x
(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2
12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.
3 × 7 = 21
12x^2 - 21 = Total sq ft of wallpaper needed for bedroom
b) First find the area of each wall.
Length: 4x, Width: 3x, Height: x
(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2
14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.
3 × 7 = 21 × 2 = 42
42x^2 - 42 = Total sq ft of wallpaper needed for living room
c) Add the two expressions to find the total amount of wallpaper needed.
(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63
26x^2 - 63 = Total sq ft of wallpaper needed for both rooms
d) Plug x = 8 into the equations found in part a and b.
12(8)^2 - 21 = 747
14(8)^2 - 42 = 854
Subtract these answers to find the difference in amount.
854 - 747 = 107
The living room needs 107 sq ft more of wallpaper than the bedroom

A park is in the shape of a rectangle 300 feet long 50 feet wide Amaya is standing at one corner of the park at point x he then walks in a straight line to the opposite corner at point y how far does he walk rounded to the nearest tenth
Answer:
[tex]304.1\ \text{feet}[/tex]
Step-by-step explanation:
The dimensions of the rectangle are 300 feet long 50 feet wide
The length between [tex]x[/tex] and [tex]y[/tex] will be the length of the diagonal of the rectangle.
Length of the diagonals can be found using the Pythagoras theorem
[tex]\sqrt{300^2+50^2}=304.138\approx 304.1\ \text{feet}[/tex]
The distance walked from [tex]x[/tex] to [tex]y[/tex] is [tex]304.1\ \text{feet}[/tex].

Step-by-step explanation:
Answer:
The answer is 1
Step-by-step explanation:
First Multiply and Divide (left to right)
3 divide by 1/3
Convert the element into a fraction:
=3/1 divided by 1/3
Apply the fraction rule:
=3/1 * 3/1
Apply rule a/1:
=3*3
Multiply the numbers: 3*3=9
=9
=9-9+1
Add and subtract (left to right):
9-9+1
9-9=0
=0+1
0+1=1

Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape.
Answer:
Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]
Step-by-step explanation:
Total fabric available = 17 yards
fraction used = one-third = 1/3
Let us convert this fraction to actual number
He used one-third of total
= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]
To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:
The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2
[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]

If f(x)=3^ x-4 what is f(- 1) ?
Answer:
1/243
Step-by-step explanation:
When you see this notation, it means plug in -1 for x in the function.
f(-1) = 3^((-1)-4)
f(-1) = 3^-5
f(-1) = 1/3^5
f(-1) = 1/243
Step-by-step explanation:
substitute (-1)
[tex] {3}^{x} - 4 \\ {3}^{ - 1} - 4 = \frac{1}{3} - 4 = - \frac{11}{3} = - 3.667[/tex]
