Answer:
the answer is A: the statement is true
It is given that Any sequence of rigid motions preserves the size of the transformed figure. Thus, This statement is true. so option A is correct.
What is rigid transformation?A rigid transformation is a transformation of the plane that preserves length. In a rigid transformation the initial shape and the image shape are congruent.
There are Main properties:
1. The distance (lengths of segments remain the same)
2. The angle measures (remain the same)
3. The parallelism (parallel lines remain parallel)
4. A collinearity (points remain on the same lines)
5. An orientation (lettering order remains the same)
It is given that Any sequence of rigid motions preserves the size of the transformed figure.
Thus, This statement is true. so option A is correct.

Answer: x = 16 and the measure of angle is 59°.
Step-by-step explanation:
Complementary angles add up to 90 degrees. Meaning that, if you add the two angles together and add them to equal 90 you can solve for x.
(x + 15) + (3x + 11) = 90 First combine like terms.
4x + 26 = 90 Subtract 26 from both sides.
-26 -26
4x = 64
x = 16
If x is equal to 16, then we can find the measure of angle N by inputting the value of x into the expression for the measure of angle N.
m∠N = 3(16) + 11
m∠N = 48 + 11
m∠N = 59

What is x?
What is y?
Answer:
x=35, y=18
Step-by-step explanation:

Use synthetic division to find (x^2+3x–4)÷(x+4)
Answer:
X^2-x- 8/x+4
Step-by-step explanation:
X+4 becomes a negative 4
Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
Which of these graphs do not represent constant rates of change? Check all that apply. On a coordinate plane, a parabola opens up. On a coordinate plane, a line has a negative slope.

Solve the system by substitution, solve by elimination. Please do both & explain. Don’t answer if you don’t know. Will mark brainliest. Thank you :)
(1)
[1] x + 5y - 4z = -10
[2] 2x - y + 5z = -9
[3] 2x - 10y - 5z = 0
Eliminate x by adding -2[1] to [2], and adding -1[2] to [3]:
-2(x + 5y - 4z) + (2x - y + 5z) = -2(-10) + (-9)
-2x - 10y + 8z + 2x - y + 5z = 20 - 9
[4] -11y + 13z = 11
-(2x - y + 5z) + (2x - 10y - 5z) = -(-9) + 0
-2x + y - 5z + 2x - 10y - 5z = 9
[5] -9y - 10z = 9
Eliminate y by adding -9[4] to 11[5]:
-9(-11y + 13z) + 11(-9y - 10z) = -9(11) + 11(9)
99y - 117z - 99y - 110z = -99 + 99
-227z = 0
z = 0
Plug this solution into either [4] or [5] and solve for y :
[5] -9y - 10(0) = 9
-9y = 9
y = -1
Plug them both into either of [1], [2], or [3] and solve for x :
[1] x + 5(-1) - 4(0) = -10
x - 5 = -10
x = -5
(2)
[1] 2x - y + z = -4
[2] z = 5
[3] -2x + 3y - z = -10
Substitute [2] into [1] and [3]:
2x - y + 5 = -4
[4] 2x - y = -9
-2x + 3y - 5 = -10
[5] -2x + 3y = -5
Solve [4] for y :
2x - y = -9
2x + 9 = y
Substitute this into [5] and solve for x :
-2x + 3(2x + 9) = -5
-2x + 6x + 27 = -5
4x = -32
x = -8
Plug this into either [4] or [5] to solve for y :
[4] 2(-8) - y = -9
-16 - y = -9
y = -5

Area of circle = 25(pi)
radius = x + 3
The value of the variable x will be 2. Then the radius of the circle will be 5.
What is the area of a circle?Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is x + 3. And the area of the circle is 25π. Then the equation will be
25π = π(x + 3)²
(x + 3)² = 25
x + 3 = 5
x = 5 - 3
x = 2
Then the radius will be
r = x + 3 = 2 + 3 = 5
The value of the variable x will be 2. Then the radius of the circle will be 5.

His parcel is a cuboid with dimensions 10 cm, 20cm and 40 cm. 20 cm 10 cm 40 cm to scale He looks at the prices of two companies, WeDeliver and GoParcels. Not drawn WeDeliver Total cost: Sum, in cm, of the 3 dimensions * £0.80 Find the cost of sending the parcel with each company. Give each of your answers
Answer:
For WeDeliver= $224
For GoParcels = $56
Step-by-step explanation:
Since we are told his parcel is a cuboid with dimensions 10cm, 20cm, and 40 cm, it means the parcel consists of 4 edges of 10 cm, 4 edges of 20 cm, and 4 edges of 40 cm.
For WeDeliver, the Total Cost is:
Sum, in cm, of the dimensions x 0.80, which is, (10cm *4) + (20cm *4) + (40cm *4) = 280cm x 0.80 = $224. While
For GoParcels, the Total Cost is:
Total area, in [tex]cm^{2}[/tex], of all 6 faces, x .02
Remember that a cuboid has six (6) faces or sides, so the total area would be gotten by taking note of the length of each visible side of the parcel and then multiplying to get the other side after which we sum after doing so we get:
[tex]800^{cm2}[/tex] for front side[tex]800^{cm2}[/tex] for the backside[tex]400^{cm2}[/tex] for the top[tex]400^{cm2}[/tex] for the bottom[tex]200^{cm2}[/tex] for the left side[tex]200^{cm2}[/tex] for the right side.Total area = [tex]2,800^{cm2}[/tex] * 0.02 = $56
