Answer:4 cm
Step-by-step explanation:
Formula for perimeter of a rectangle: P = 2(l+w)
20 = 2(6+w)
20 = 12+2w
divide by 2
10 = 6 + w
10-6 = w
4 = w

Last week Betsy made 80 on her quiz. This week she made 76. What is the percent of decrease in her score?
Answers
From the information given, she made an 80 the first week she took the quiz, then the next week she made a 76. Furthermore, we are asked to find the percent decrease.
Decrease means less. And less means subtraction in terms of Mathematics. So, hence, subtract 76 from 80 to find the percent decrease.
80 - 76 = 4
Now, just add the percentage behind the result.
4%
Therefore, the percent decrease in Besty's score is 4%.

Answer:
g(x) = 14x +7g(x) = 7x -18g(x) = -7x -16g(x) = 21x +17Step-by-step explanation:
The transformations of interest here are ...
g(x) = b·f(x) . . . . vertical scaling by a factor of bg(x) = f(-x) . . . . . reflection across the y-axisg(x) = f(x -h) +k . . . translation h units right and k units up1. The transformation parameters are given as b=2, (h, k) = (0, -3). Then we have ...
f1(x) = 2f(x) = 2(7x +5) = 14x +10 . . . . . vertical stretch by 2
g(x) = f1(x -0) -3 = 14(x -0) +10 -3
g(x) = 14x +7
__
2. (h, k) = (3, -2)
g(x) = f(x -3) -2 = 7(x -3) +5 -2 = 7x -21 +3
g(x) = 7x -18
__
3. The reflection gives us ...
f1(x) = f(-x) = 7(-x) +5 = -7x +5
Then the translation 3 left is (h, k) = (-3, 0).
g(x) = f1(x -(-3)) +0 = -7(x +3) +5 = -7x -21 +5
g(x) = -7x -16
__
4. The transformation parameters are b = 3 and (h, k) = (0, 2).
f1(x) = 3f(x) = 3(7x +5) = 21x +15 . . . . . . vertical stretch by 3
g(x) = f1(x) +2 = 21x +15 +2
g(x) = 21x +17

Use the distributive property to remove the parentheses.
-3(-6y +3w-2)
Answers
Answer:
18y-9w+6
Step-by-step explanation:
-3*-6y=18y
-3*3w=-9w
-3-2=6
so, 18y-9w+6
Answer:
18y-9w+6
Step-by-step explanation:
The distributive property tells that because the -3 is outside of the parentheses, we multiply all values inside the parentheses by -3.
So, -6y * -3 is 18y because two negatives cancel out, 3w * -3 equals -9w, and -2 * -3 is 6, again because two negatives cancel each other out.
We put this all together, the parentheses and -3 is removed, and the expression becomes 18y-9w+6.
What is the answer to 4(-x + 4) =12
Answers
Solution:
-4x + 16 = 12
-4x = 4
x = -1
Hey there!
4(-x + 4) = 12
4(-x) + 4(4) = 12
-4x + 16 = 12
SUBTRACT 16 to BOTH SIDES
-4x + 16 - 16 = 12 - 16
CANCEL out: 16 - 16 because it gives you 0
KEEP: 12 - 16 because it helps solve for the x-value
NEW (temporary) EQUATION: -4x = 12 - 16
12 - 16 = -4
NEW EQUATION: -4x = -4
DIVIDE -4 to BOTH SIDES
-4x/-4 = -4/-4
CANCEL out: -4/-4 (the LEFT side) because that gives you 1
KEEP: -4/-4 (the RIGHT side) because it gives you the result of the x-value
x = -4/-4
x = 1
Therefore, your answer is: x = 1
