Answer:
AB=8
Step-by-step explanation:
First, you get figure out x. Since both sides are equal, use the equation x+3=2x-2, then subtract x from both sides, 3=x-2, and then add 2 to both sides, x=5. Then use one of the equations to get the length of the side, I used x+3=8, which is your answer.

EFGH is a parallelogram. Find the measure of EG. parallelogramefghmsidesw7 The measure of EG is .
Answers
Answer: EG = 80
Step-by-step explanation: A parallelogram is a quadrilateral with opposite sides parallel to each other.
The diagonals of a parallelogram bisect each other, which means, using the figure as example:
EJ = JG
So, to determine EG, first find w:
[tex]4w+4=2w+22[/tex]
[tex]2w=18[/tex]
w = 9
Substituting:
[tex]EJ=4w+4[/tex]
[tex]EJ=4(9)+4[/tex]
EJ = 40
Since each segment has the same measure:
EG = 2EJ
EG = 2(40)
EG = 80
The measure of EG is 80 units

The placemats are to be rectangular in shape with an area represented by
45x2 - 71% - 150. The width of each placemat is represented by 5x + 6. The expression to
represent the length of each placemat can be determined by the formula,
length = area = width. Which expression can Alicia use in the programming to represent the
length of each placemat?

9x - 25
B
9x + 25
C 45x2 - 66x - 144
D 9x2 - 14.2x - 30
Answers
Answer:
A
Step-by-step explanation:
The expression for the width of rectangular placemats is (9x - 25) units.
Given that, the area of rectangular placemats=45x²-70x-150.
What is the area of a rectangle?The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, the area of the rectangle = (a × b) square units.
Now, 45x²-70x-150=(5x + 6)×b
⇒b=45x²-75x-150/(5x + 6)
⇒b=(5x + 6)(9x - 25)/(5x + 6)
⇒b=(9x - 25)
Therefore, the expression for the width of rectangular placemats is (9x - 25) units.

Hi, how to do question 10:)?
Answers
Step-by-step explanation:
For the cubic function to be an increasing function, dy/dx > 0 for all real values of x.
dy/dx
= d/dx [4x³ + 4px² + 16x - 9]
= 12x² + 8px + 16.
We have 12x² + 8px + 16 > 0.
=> 3x² + 2px + 4 > 0,
where a = 3, b = 2p and c = 4.
For the quadratic function to have a range that is always positive, the discriminant must be less than 0.
(in order to have no real roots)
We have b² - 4ac < 0.
=> (2p)² - 4(3)(4) < 0
=> 4p² - 48 < 0
=> p² - 12 < 0
=> p² < 12
=> -√12 < p < √12
=> -2√3 < p < 2√3.
That was a very long process but hopefully you understand all of it!

Answer:

The fraction of the trees that is between 4.0 and 4.4 feet is 7%
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
x is the raw score, μ is mean and σ is standard deviation
Given that μ = 3.2, σ = 0.6, hence:
[tex]For\ x = 4:\\\\z=\frac{4-3.2}{0.6} =1.33\\\\\\For\ x = 4.4:\\\\z=\frac{4.4-3.2}{0.6} =2[/tex]
From the normal distribution table, P(4 < x < 4.4) = P(1.33 < z < 2) = P(z < 2) - P(z < 1.33) = 0.9772 - 0.9082 = 7%
The fraction of the trees that is between 4.0 and 4.4 feet is 7%

Suppose M is the midpoint of FG. Find the missing measure.
MG = 13x + 1, FG = 15
Answers
Answer:
14 - 13x
Step-by-step explanation:
take 13x + 1 away from 15
15 - (13x + 1) = 15 - 13x - 1 = 14 - 13x
The value of x is 1/2 and the measure of MG is 7.5 cm.
Given that, M is the midpoint of FG.
We need to find the measure of MG and FM.
What is the midpoint of a line segment?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Now, FG=MG+FM
⇒FG=MG+MG (MG=FM)
⇒FG=2MG
⇒15=2(13x+1)
⇒15=26x+2
⇒x=1/2
Now, MG=FM=13(1/2)+1=7.5 cm
Therefore, the value of x is 1/2 and the measure of MG is 7.5 cm.

Looking at the options:
We see that Symmetric property states that if a = b then b= a
Same is the case with the question.
We have :

Emily and Chelsea each improved their yards by planting hostas and shrubs. They bought their supplies from the same store. Emily spent $132 on 6 hostas and 12 shrubs. Chelsea spent $213 on 14 hostas and 9 shrubs. Find the cost of one hosta and the cost of one shrub.
Answers
Answer:
One hosta = $ 12 , One shrub = $ 5
Step-by-step explanation:
Let;
x = hostas
y = shrubs
Emily spent $132 on 6 hostas and 12 shrubs.
6x + 12y = 132 ........................................ (i)
Chelsea spent $213 on 14 hostas and 9 shrubs
14x + 9y = 213 ........................................ (ii)
From (i)
12y = 132 - 6x
y = 11 - 0.5x ........................................ (iii)
substitute (iii) into (ii)
14x + 9 (11 - 0.5x) = 213
14x + 99 - 4.5x = 213
9.5x = 114
x = $ 12
Substitute value of x in (iii)
y = 11 - 0.5(12)
y = 11 - 6 = $ 5
