To calculate perimeter (borderline) of the rectangle use: 2(l+b). ‘It’s the same as adding the length of all four sides, you can do that too’
To calculate the area of a rectangle the formula is length*width
Now let’s look at the question. For part a it asks us to wrap ribbon *around* the mirror
This means the length of the ribbon will be the same as the perimeter of the mirror
Perimeter=
2(6+10)
= 2(16)
= 32 inches
For part be we have to find the area so:
Length * width
6 * 10 inches
= 60 inches
Hope this helps

For what values of x is the equation x2−x=20 true?
Answers
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
For what values of x is the equation x² − x = 20 true?
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex] \sf \: x ^ { 2 } - x = 20[/tex]
Subtract 20 from both sides.
[tex] \sf \: x^{2}-x-20=0 [/tex]
To solve the equation, factor [tex]\sf\: x^{2}-x-20[/tex] using formula [tex]\sf\:x^{2}+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right)[/tex]. To find a and b, set up a system to be solved.
[tex] \sf \: a+b=-1 \\ \sf \: ab=-20 [/tex]
As ab is negative, a and b have the opposite signs. As a+b is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product -20.
[tex] \sf1,-20 \\ \sf 2,-10 \\ \sf4,-5 [/tex]
Calculate the sum for each pair.

Answers
Answer:
Image result for The length of a rectangle is 3 more than five times its width. If the perimeter of the rectangle is 30 meters, find the dimensions of the rectangle.
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Find set
A={1, 2, 6, 10}
B={3, 6, 9, 10, 11}
C = {1, 2, 4, 7, 11}
Answers
If U = {1, 2, 3, …, 12} is the universal set, and
A = {1, 2, 6, 10}
B = {3, 6, 9, 10, 11}
C = {1, 2, 4, 7, 11}
then
(1) A U B is the set containing all elements from A and B,
A U B = {1, 2, 3, 6, 9, 10, 11}
(2) A ∩ B is the set of elements that are contained in both A and B,
A ∩ B = {6, 10}
(3) Unfortunately, A ∩ B U C is somewhat ambiguous. It could mean (A ∩ B) U C or A ∩ (B U C ). Then either
(A ∩ B) U C = {6, 10} U {1, 2, 4, 7, 11} = {1, 2, 4, 6, 7, 10, 11}
or
A ∩ (B U C ) = {1, 2, 6, 10} ∩ {1, 2, 3, 4, 6, 7, 9, 10, 11} = {1, 2, 6, 10}
The first interpretation is probably the intended one, since that essentially reads the set operations from left to right.
(4) A' U B is the union of A' and B, where A' is the complement of A, or all elements in U that are not in A. We have
A' = U - A = {3, 4, 5, 7, 8, 9, 11, 12}
and so
A' U B = {3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
(5) We have
A U C = {1, 2, 4, 6, 7, 10, 11}
so that
(A U C )' = U - (A U C ) = {3, 5, 8, 9, 12}
(6) We have
B' = U - B = {1, 2, 4, 5, 7, 8, 12}
and so
A ∩ B' = {1, 2}
(7) Using the complements found in (4) and (6), we have
A' U B' = {1, 2, 3, 4, 5, 7, 8, 9, 11, 12}
Alternatively, we can use the fact that
A' U B' = (A ∩ B)'
and since we know from (2) that A ∩ B = {6, 10}, we end up with the same result,
(A ∩ B)' = U - (A ∩ B) = {1, 2, 3, 4, 5, 7, 8, 9, 11, 12}
(8) We have
A U B U C = {1, 2, 3, 4, 6, 7, 9, 10, 11}
so that
(A U B U C )' = {5, 8, 12}

Answers
8 - (3 + b) = b - 9
Opening the brackets changes the symbol to it's opposite symbol, which gives us
8 - 3 - b = b - 9
By using the transposition method, we get
8 - 3 + 9 = b + b
or, 14 = 2b
or, 14/2 = b
or, 7 = b
The value of b is 7.

Answer: the answer is in the screenshot
Step-by-step explanation:
The hypotenuse of each set of legs of a right triangle are:
1. 5 and 6 => √61
2. 4 and 1 => √17
3. 2 and 5 => √29
4. 9 and 12 => 15
What is the Hypotenuse?In a right triangle, the hypotenuse is the longest side that is opposite to the right angle. The hypotenuse can be determined by finding the square root of the sum of the other two legs.
1. √(5² + 6²) = √61
2. √(4² + 1²) = √17
3. √(2² + 5²) = √29
4. √(9² + 12²) = 15

The text of the Pythagorean Theorem The Pythagorean Theorem states: “The sum of the squares of the lengths of the two sides of the right triangle, which are the shortest sides in a right-angled triangle, is equal to the square of the length of the hypotenuse, which is the longest side of the triangle.”
And in symbols: Pythagorean theorem = ( A² + B² = C²)
where ;
● A, B: the two sides of a right triangle ABC.
● C: The hypotenuse of a right triangle is ABC, which is the longest side.
It should be noted that the inverse of the theory is also true; Since the triangle to which the Pythagorean theorem applies, namely: A² + B² = C², is necessarily a right-angled triangle.
