46. The midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.
Using this info,
We already know EF=11 so
[tex] \frac{1}{2} (8 + 2x - 4) = 11[/tex]
[tex]x + 2 = 11[/tex]
[tex]x = 9[/tex]
53. Apply Midpoint Formula
[tex]( \frac{x1 + x2}{2} \: and \: \frac{y1 + y2}{2} )[/tex]
Let find the midpoint of each side
KL (+2a/2, +2a/2), LM(-2a/2, 2a/2) MN(-2a/2, -2a/2) NK(2a/2, -2a/2)
So the midpoint of each side is
KL=(a,a)
LM= (-a,a)
MN=(-a,-a)
NK=(a,-a).
The slopes of these line is y2-y1/x2-x1
KL=2a/-2a=-a
LM=-2a/-2a=a
MN=-2a/2a=-a
NK=-2a/-2a=a
Let find the length of all sides. Since each coordinate has a form of 0 in it, we would just consider the finite value, 2a.
Distance of all sides are 2a.
Consider the midpoint, notice how each midpoint can be obtained by a rotation of 90-180-270 or 360 degrees about the origin of one of the midpoints. Since all the side lengths and slope are equal, a rigid transformation like a rotation would preserve the side lengths and midpoint of each line. It also proves rotational symmetry and the only 4 figure quadralaterial that has a 90,180,270, and/or 360 degrees rotational symmetry is a square.

Step-by-step explanation:
3x-3+x=4x-3
First you need to combine like terms on the left side of the equation
3x-3+x the like terms are 3x and x, remember there is always an invisible 1 next to x
add them:
3x+x=4x
so now we have
4x-3=4x-3
- we are subtracting 3 on both sides of the equation add 3 to cancel out the three
4x-3 4x-3
+3 +3
- The threes cancel out so we are left with
4x=4x
x=0

a museum director wants to hang the painting on a wall. To the nearest foot, how tall does the wall need to be.
the painting is the square root of 90 ft
help!
Answers
Answer:
10ft
Step-by-step explanation:
I'm not quite sure I understand your question because you seem to have already stated the height of the wall but I found a similar one (see attached).
If the height of the picture is √90 feet. This means it is;
√90 = 9.5 ft
Rounded to the nearest foot is 10 feet.
To be able to hang the painting, the wall would have to be at least 10 ft in height.
The height of the wall should be at least 9.5 feet.
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a museum director wants to hang the painting on a wall the height of the painting is √90 feet.
Height = √90
Height = 9.48 feet
Therefore, the height of the wall should be at least 9.5 feet.

What is 75% of 400? Write and evaluate an expression
to find the answer. Then explain how to use the model
to justify the answer
Answers
Answer:
The answer is 300
Step-by-step explanation:
so first you do 100% of 400 which is 400 then you do 400 divided by 4 because it is counted from 25%, 50%, 75%, and 100%.
after that when u get the answer for 400 divided by 4 which is 100 you do 100 times 3 which is 300.
hope this helps :D
Answer:
75% of 400 is 300. Equation- (75×400) ÷ 100=300 (Im not sure what the model is because it was not included in this question but hopefully this helped solve the first part of your question.)
Step-by-step explanation:
Multiple 75*400
You would get 30,000, then take that 30,000 and divide it by 100
You get 300, which is the answer for the first part of the question.

The number of eggs will be 28, which Bridget collected from the chickens this morning.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that, Bridget collected the eggs her chickens had laid and gave ½ to her neighbor.
The equation below represents Bridget's original collection.
⇒ (e/2) - 6 = 8
⇒ e/2 = 8 + 6
Apply the addition operation,
⇒ e/2 = 14
Multiply by 2 into both sides of the above equation
⇒ 2 × e/2 = 2 × 14
⇒ e = 28
Therefore, the number of eggs will be 28, which Bridget collected from the chickens this morning.

if you mean x multiply 2 :
j(x) = 2x + 1
j(a+1) = 2(a+1) + 1
= 2a+ 2 +1
=2a + 3
if you mean x to the power of 2
j(x) = x^2 +1
j(a+1) = (a+1)^2 + 1
= a^2 + 2a + 1 +1
= a^2 + 2a + 2
