Using squares 1, 2, and 3, and eight copies of the original triangle, you can create squares 4 and 5. Keep the square 4 and square 5 window open. You will need them to complete the rest of the tasks in this section. What are the side lengths of square 4 and square 5 in terms of a and b? Do the two squares have the same area?
Using squares 1, 2, and 3, and eight copies of the original triangle, you can create squares 4 and
Answer:
Step-by-step explanation:
The 4 sides of a square are usually the same ;
Hence, each side is called the side length ; from the diagram attached :
Side length of square 4 = a + b
Side length of square 5 = a + b
If the side lengths are equal ; that is (a + b) ; the the area which is the square of the side length will also be the same.

A construction crew is lengthening a road. Let y represent the total length of the road (in miles). Let x represent the number of days the crew has worked.
Suppose that x and y are related by the equation y = 53+2x.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
What is the change per day in the road's length?
miles
What was the road's length when the crew started working?
Answer: The equation y = 53+2x relates the variables x and y, where x represents the number of days the crew has worked and y represents the total length of the road.
The change per day in the road's length is given by the coefficient of x in the equation, which is 2. Thus, the change per day in the road's length is 2 miles.
The road's length when the crew started working is given by the constant term in the equation, which is 53. Thus, the road's length when the crew started working was 53 miles.

A boat will pass the Colby bridge and the wave bridge on the dell river. Rename each other the two bridge opening times. there are 60 minutes in an hour so use 60 as a common denominator. Then rename each opening time and find another common denominator. Explain how you found your answers.
The bridge opening times when there are 60 minutes in an hour will be 45/60 and 10/60.
How to illustrate the fraction?From the information, a boat will pass the Colby drawbridge and then the Wave drawbridge and then the Wave drawbridge.
From the table, Colby is on the 3/4 hour. This will be:
= 3/4 × 60
= 45
Also, Wave Bridge will be:
= 1/6 × 60
= 10
Therefore, it's 45/60 and 10/60 because we know that the common denominator is 60 then 3/4 of an hour is 45mins then 1/6 of an hour is 10.

Consider the function G(x)=x^2 + 7x – 18/x^2+2x-8
Which type of discontinuity does the function have at x = -4?
1.jump
2.mixed
3.infinite
4.removable
Answer:
it is an infinite discontinuity.
Step-by-step explanation:
Removable type of discontinuity does the function have at x = -4. Option 4 is correct.
What is the definition of removable discontinuity?If the limit of the function at the place of discontinuity exists and the value of the function exists, but they are not equal to each other, the discontinuity is removable.
We may eliminate the discontinuity by making the function's value equal to the function's limiting value at that time.
The given function is;
G(x)=x²+ 7x – (18/x)²+2x-8
G(-4)=(-4)²+7×(-4)- (18/-4)²+2(-4)-8
G(-4)=16-28-20.25-8-8
G(-4)=16-64.25
G(-4)=- -48.25
The given data on putting the value gives the negative values.
Hence, the removable type of discontinuity does the function have at x = -4

) Find the coordinates of the point A' which is the symmetric point
A(3. 2) with respect to the line 2.x + y - 12 = 0.
Let, coordinate of point A' is (x,y).
Since, A' is the symmetric point A(3, 2) with respect to the line 2x + y - 12 = 0.
So, slope of line containing A and A' will be perpendicular to the line 2x + y - 12 = 0 and also their center lies in the line too.
Now, their center is given by :
[tex]C( \dfrac{x+3}{2}, \dfrac{y+2}{2})[/tex]
Also, product of slope will be -1 .( Since, they are parallel )
[tex]\dfrac{y-2}{x-3} \times -2 = -1\\\\2y - 4 = x - 3\\\\2y - x = 1[/tex]
x = 2y - 1
So, [tex]C( \dfrac{2y -1 +3}{2}, \dfrac{y+2}{2})\\\\C( \dfrac{2y + 2}{2}, \dfrac{y+2}{2})[/tex]
Also, C satisfy given line :
[tex]2\times ( \dfrac{2y + 2}{2}) + \dfrac{y+2}{2} = 12\\\\4y + 4 + y + 2 = 24\\\\5y = 18\\\\y = \dfrac{18}{5}[/tex]
Also,
[tex]x = 2\times \dfrac{18}{5 } - 1\\\\x = \dfrac{31}{5}[/tex]
Therefore, the symmetric points is[tex]A'(\dfrac{31}{5}, \dfrac{18}{5})[/tex] .

The value of (2/3 - 5/6) / 3/4 is -2/9.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
(2/3 - 5/6) / 3/4
2/3 - 5/6
= (4 - 5)/6
= -1/6
Now,
(-1/6 )/(3/4)
= -1/6 x 4/3
= -4/18
= -2/9
Thus,
The value is -2/9.
