A farmer wants to build two fenced-off sections within his field, one in the shape of a rectangle and the other in the shape of a square. The side of the square must be equal to the width of the rectangle, x feet. The length of the rectangle must be 50 feet longer than its width. The field the farmer wants to build the two fenced sections in has an area of y square feet. The difference of the area of this field and the area of the fenced, square section needs to be at least 1,000 square feet. In addition, the sum of the fenced areas must be less than the area of the field. This is the system of inequalities that represents this situation. Which points represent viable solutions?

Emily and Zach have two different polynomials to multiply:
Polynomial product A:
(4x2 – 4x)(x2 – 4) Polynomial product B:
(x2 + x – 2)(4x2 – 8x)
They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

The point (17,−9) is translated to the point (6,2). Select the description of the translation.
A
9 down, 7 right.
B
11 left, 11 up
C
9 right, 11 up
D
11 left, 9 down plzzz answer..
Answer:
11 up , 11 left
Step-by-step explanation:
Given
[tex](17, -9)[/tex] to [tex](6,2)[/tex]
Required
Determine the translation rule
Considering the x coordinates.
From 17 to 6
6 is to the left of 17.
Using the translation rule:
[tex]x = x' + b[/tex]
[tex]17 = 6 + b[/tex]
[tex]17 - 6 = b[/tex]
[tex]11 = b[/tex]
[tex]b = 11[/tex]
Hence: From 17 to 6 is 11 units left translation
Considering the y coordinates.
From -9 to 2
2 is at the top -9.
Using the translation rule:
[tex]y = y' + b[/tex]
[tex]-9 = 2 + b[/tex]
[tex]-9 - 2 = b[/tex]
[tex]-11= b[/tex]
[tex]b = -11[/tex]
The negative value impies a upward translation.
Hence: From -9 to 2 is 11 units up translation

Step-by-step explanation:
2x(x + y) + 2(x2 + 3xy)
Answer:
4x² + 8xy
Step-by-step explanation:
Given
2x(x + y) + 2(x² + 3xy) ← distribute both parenthesis
= 2x² + 2xy + 2x² + 6xy ← collect like terms
= 4x² + 8xy
The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
Answer:
The images of the question are missing, I found a matching question and image online, and it is in the attachments.
Answer:
The scale factor of the triangles from the left to the right is 2
or
The scale factor of the triangles from the right to the left is 1/2
Step-by-step explanation:
From the image, the right triangle on the left has the following dimensions:
Hypotenuse = 10
length of one side = 10
While the right triangle on the right has the following:
Hypotenuse = 20
Length of one side = 20
From the dimensions above it can be seen that the triangle on the right has a dimension of 2 times the triangle on the left:
Left (10) × 2 = right (20)
Therefore the scale factor of the triangles from the left to the right is 2
or
The scale factor of the triangles from the right to the left is 1/2

Rebecca saved AED 175.30 in June and AED 132.50 in July. Then she bought a bicycle for AED 195.80. How much of her savings from June and July was left?
Answer:
her saving that was left from June and July is 112
Step-by-step explanation:
The computation of the saving amount left is shown below;
= Total saving in 2 months - amount spent
= 175.30 + 132.50 - 195.80
= 112
Hence, her saving that was left from June and July is 112
3. Cindy's ice cream looks pretty normal. It is shaped like a cone topped with a half-sphere. The cone
has a height of 11 in and a radius of 6 in.
What is the approximate volume of the whole shape? Round your answer to the nearest tenth. Use
3.14 to approximate pi. (Show your work.)
Answer:
Answer: 284.7
Step-by-step explanation:
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
