Lucia draws a square and plots the center of the square, She claims that any rotation about
the center of the square that is a multiple of 45° will carry the square onto itself
Which statement best describes Lucia's claim?
A. Lucia's claim is correct since any rotation that carries a square onto itself is a multiple of 45°,
B. Lucia's claim is correct since any rotation that is a multiple of 45° carries a square onto itself
C. Lucia's claim is incorrect since not all rotations that carry a square onto itself are multiples of 45,
D. Lucia's claim is incorrect since not all rotations that are multiples of 45° carry a square onto itself
Answer:
The 2 si right
Step-by-step explanation:
We want to study the symmetry of a square and which rotations carry the square into itself.
We will see that the correct option is the last one:
Not all rotations of multiples of 45° carry the square into itself.
Here we have the claim:
" any rotation about the center of the square that is a multiple of 45° will carry the square onto itself"
And we want to see if this is true or not.
What we can try to do, is find a counterexample to see if this is false.
Let's draw a square, then make a point in the center of it, and draw a segment between the center and the right side.
Now rotate that segment around the center of the square (and along with it, the whole square) by 45°.
(note that 45° is a multiple of 45°).
Doing this, you will see that this rotation does not rotate the square into itself.
So the correct option is D, not all rotations of 45° rotate the square into itself. While rotations of 90°, 180°, 270°, etc... will map the square into itself, we just found an example of a rotation of a multiple of 45° that does not do it.
An image of the rotation can be seen below:

Find the slope of the line.
1/3
-1/3

-3
Answer:
if a line is like so it has a positive slope: / . IF a line is like this it has a negative: \
Therefore that leaves out -1/3 and -3
Either A or C is correct
From the y intercept (where the line intercepts the y axis), in this case 2, to the next point on the line (3, 3) it goes up 1 and over 3 to get to that point from the intercept. Therefore the slope is 1/3. (Rise/run)

Use the number line. Enter the integer value that point D represents.
Number line from -10 to 10 with 20 tick marks. Point D is 1 tick mark to the left of 5.
Given:
A number line from -10 to 10 with 20 tick marks.
Point D is 1 tick mark to the left of 5.
To find:
The integer value that represents point D.
Solution:
A number line from -10 to 10 with 20 tick marks. It means, each mark represents the integer values from -10 to 10.
We know that, as we move towards left on a number line the value decreases and as we move towards right the value increases.
Point D is 1 tick mark to the left of 5. It means, point D represents the integer value which is 1 less than 5.
[tex]5-1=4[/tex]
Therefore, point D represents the integer 4.

What is rectangular prism ?Connect three rectangles edge to edge. To close their triangular mouths from both ends. That shape is called a triangular prism.
A rectangular prism has six faces (each one of these faces are rectangle), 8 vertices, and 12 edges.
Noted that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters ().
Considering that all these layers are equal, the volume of this prism can be calculated with:
Volume = Base area x length
= 1/2 x 6 x 4 x 10
= 240/2
= 120

What’s is value of x
Answer:
x= -16
Step-by-step explanation:
-3x-8/ 4 = 10
Here we can try to isolate x and so we have to first multiply 4 on each side.
-3x-8= 40
Then we can add the 8 to each side.
-3x= 48
Next, divide the -3 onto each side and we can get the answer!
x= -16

Step-by-step explanation:
edge
Iliana will be able to construct a triangle because the sum of any two sides is greater than the third side.
How to determine the correct statement?The sides of the triangle are given as:
12, 36 and 39.4 inches
According to the triangle inequality theorem, the following must be true
x + y >= z
Where z is the longest side.
This means that:
12 + 36 >= 39.4
Evaluate the sum
48 >= 39.4
The above inequality is true
Hence, the true statement is (c)

Identify the error in this column:
(x2 + 3x + 18) = (x + 3)(x + 6)
Answer:
The error is found in the "3x" part of the equation.
Step-by-step explanation:
The rest of the equation is correct because x times x = x2. And 6 times 3 = 18. But x times 6 = 6x, and 3 times x = 3x, and 6x+3x=9x. 9x doesn't = 3x
Answer:
It should be 9x instead of 3x on the left-hand side of the equation.
Step-by-step explanation:
We can expand the equation (x+3)(x+6) to find out:
(x+3)(x+6) = x² + 6x + 3x + 18
We multiply x with x then x with 6.
Then, we multiply 3 with x and 3 with 6.
x² + 6x + 3x + 18 = x² + 9x + 18
