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 ratios 9:18, 12:24, 15:30, 18:36, and 21:42 form a pattern of equivalent ratios in the table below.
A multiplication table. In the row labeled 3, the numbers 9, 12, 15, 18, and 21 are highlighted. In the row labeled 6, the numbers 18, 24, 30, 36, and 42 are highlighted.
Which is another ratio in this pattern?
1:3
6:12
24:27
28:49
Answer:
6:12
Step-by-step explanation:
the bottom row is in multiples of 3
top is multiples of 2
and they must be double from the neumerator so the answer is 6:12
Which answer choice represents an equivalent number sentence of "49 - 12"?
A. 37
B. 49 + (-12)
C. 49 + 12
D. 12 - 49
Answer:
B
Step-by-step explanation:
A. 37 isn't a number sentence
B. 49 + (-12) = 49-12. They're the same thing because 49 minus 12 can also be written as 49 plus negative 12
C. 49 + 12 doesn't equal 49-12
D. 12- 49 = -37 which isn't equivalent to 49-12.

1.Write the arithmetic sequences that would find the nth term.
2.Using the formula you created, what is the 15th term?
if you cant see the numbers on the chart they are.....
N 1 2 3 4 5
f(n) 155 141 127 113 99
Answer:
-14
Step-by-step explanation:
Start at 99 (5th number) and keep subtracting 14 until you get down to the 15th number. Then once you keep subtracting you will get -14. But there are negative numbers after the 12th number. So you might have to deal with those... but overall you got it! <3

1.Write the arithmetic sequences that would find the nth term.
2.Using the formula you created, what is the 15th term?
Answer:
f(n) = 155 - 14(n-1) [Question 1, Arithmetic sequence]
f(15) = -41 [Question 2, 15th term]
Step-by-step explanation:
Given the explicit formula for an arithmetic sequence: f(n) = f(1) + d(n-1).
Where d is the common difference, f(n) is the nth term, and f(1) is the first term.
Given that the first term f(1) is 155 from the table since 1 is n, and 155 is f(n). And the second term f(2) is 141 since n is 2, and 141 is under f(n) on the table when n is 2.
Subtract the two terms to find the common difference: d = f(2) - f(1) = f(3) - f(2) = f(4) - f(3) = ...
d is 155-141= -14.
Remember how the first term in the sequence is 155, and how d is -14, we can make this into an equation:
f(n) = f(1) + d(n-1) → f(n) = 155 - 14(n-1).
We can test this by matching the equation by input, and output to the table:
f(1) = 155 - 14(1-1) = 155
f(2) = 155 - 14(2-1) = 155 - 14 = 141
f(3) = 155 - 14(3-1) = 155 - 28 = 127
f(4) = 155 - 14(4-1) = 155 - 42 = 113
f(5) = 155 - 14(5-1) = 155 - 56 = 99
......
f(15) = 155 - 14(15-1) = 155 - 196 = -41
