1. If the scale factor between the original and the image is 4, how many times larger is the perimeter of the image than the original?
2. If the scale factor between the original and the image is 0.5, how many times is the perimeter of the image than the original?
3.The perimeter of an original figure is 14. If the image has a scale factor of 6 from the original, what is the perimeter of the image?
4.The perimeter of an original figure is 64. If the image has a scale factor of 0.25 from the original, what is the perimeter of the image?
Answers
Problem 1
Answer: New perimeter is 4 times larger than the original
----------
Explanation:
This is because we are multiplying each side by 4 to make each side 4 times larger than the original.
Let's say we had a triangle with side lengths 1,2,3
The perimeter would be 1+2+3 = 6
Now multiply each side by 4
4*1 = 4
4*2 = 8
4*3 = 12
Then add up those new side lengths: 4+8+12 = 24
We see that 24 is exactly 4 times larger than 6
In more general terms, say the triangle has side lengths x y and z
The old perimeter is simply x+y+z
The new perimeter is 4x+4y+4z = 4(x+y+z) = 4*(original perimeter)
==========================================
Problem 2
Answer: New perimeter is 0.5 times larger than the old perimeter
In other words, the new perimeter is half as large
----------
Explanation:
The same idea applies as in problem 1. The only difference is that we're multiplying each side by 0.5 now
1/2 = 0.5
==========================================
Problem 3
Answer: 84
----------
Explanation:
We're using the same idea as the other problems above.
new perimeter = (scale factor)*(old perimeter)
new perimeter = (6)*(14)
new perimeter = 84
==========================================
Problem 4
Answer: 16
----------
Explanation:
Same idea as before
new perimeter = (scale factor)*(old perimeter)
new perimeter = (0.25)*(64)
new perimeter = 16
As you can see, if the scale factor is larger than 1, then the new perimeter will be larger. If the scale factor is smaller than 1, but still positive, then the new perimeter will be smaller.
Answer: The scale Factor is the number that you Multiply the Original Lengths by to get the new lengths.
1.) The new length is 4 times the original. 4× L
2.) The new length is 0.5 times the original. 0.5× L
3.) 84. 6×14 = 84
4.) 16. 64× 0.25 = 16
Step-by-step explanation:
For lines --- like sides, perimeter, and distance, Multiply the original number by the Scale Factor to get the new number. Or Divide the New number by the Scale Factor to get the Original.
(They ask that sometimes.)
__Also remember that length refers to lines__.
[ Area refers to Square Units. The Factor must also be squared. ]

The dimensions of a rectangular dining room are 18 feet by 16 feet. If a scale factor of One-fourth is used to make a scale model of the dining room, what is the area of the dining room in the scale model?
18 square feet
36 square feet
48 square feet
72 square feet
Answers
Given -
The dimensions of a rectangular dining room are 18 feet by 16 feet. i.e, length (l) = 18 feet and breadth (b) = 16 feetScale factor of One-fourth is used to make a scale model of the dining room.To find -
the area of the dining room in the scale model (A)Solution -
As we know, the area of rectangle = length of the rectangle × breadth of the rectangle
To state the dimensions of the scale model we will multiply 1/4 with the already given dimensions of a rectangular dining room. Hence, dimensions of scale model is 18/4 by 16/4.
Now,
Area = length × breadth
Area = 18/4 × 16/4 square feet
Area = 18 square feet
Therefore, the area of the dining room in the scale model (A) is 18 square feet.

4. Write the equation of the line in standard form.
5. Give the x-intercept from standard form (remember, let y=0)
6. Give the y-intercept from standard form (remember, let x=0)
Answers
Answer:
The slope of the line is m = −11/3 ≈ −3.66666666666667 .
Step-by-step explanation:
The slope of a line passing through two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=−6, y1=7, x2=−3, y2=−4.
Plug the given values into the formula for a slope: m=−4−(7)−3−(−6)=−113.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=7−(−113)(−6)=−15
Finally, the equation of the line can be written in the form y=b+mx:
y=−15−11x3

4x + 6y = 865 and 6 are supplementary angles and sum up to 180 as per definition of supplementary angles
5x + 6y + 86 = 180 ⇒ 5x + 6y = 94Comparing the two equations
6y = 86 - 4x and 6y = 94 - 5x86 - 4x = 94 - 5x5x - 4x = 94 - 86x = 8Finding y
