Answer:
I think Its D because In the rectangular base its not equal sides like a square so it would be more be like sides that are not perpendicular
Step-by-step explanation:

Step-by-step explanation:
triangle area is 1/2BH
1/2(4x)=4
2x=4
x=2 units
Answer:
Missing side = 2
X= 2
Have given details if x was only base of the side triangle
This is in order to find a completely new triangle with just the height and in order to find and combine 1 given area say if just the right side in your diagram was 4 and we had to find the other triangle. This is only done on scale or 1 given measure or angle for the right side triangle. We was not given this but proved a 0.3 scale.
Area of other triangle =2.66^2
2.66+4 combined = 6.66^2
Step-by-step explanation:
We find a square height is also 4
We also know a right angle triangles height can be found using either 1/2 base or 1/2 height.
So this can mean the height is and stays 4 and the base is 2.
As 1/2 4 height = 2 height
2 unit height x 2 unit base = 4
Therefore, the first triangle slant is the same.
4sq +2sq = c^2
√16+√4 = √20
c^2 = √20 = 4.47 = 4.472135955
c = 4.47 slant
Given a=4 and c=4.47,
b = 1.99522
∠α = 63.49° = 63°29'23"
∠β = 26.51° = 26°30'37"
h = 1.78543
We cna tell now that the triangle is 0.333 smaller so the measurements
Show 2/3 of 2 = 1.333 being the base across
using this as Area we find 1.333 x 2 = 2.666
(1/2 h^b of 4) =2
We can prove with the angles
63 +27 degree or
a^2+b^2 = c^2
1.333^2 + 4^2
= √1.776889+√ 16 = √ 17.776889
c^2 = 4.21626481616
c= 4.22 slant left side (nb right side on attachment)
Angle ∠ A = α = 71.478° = 71°28'39″
Angle ∠ B = β = 63.53° = 63°31'48″
Angle ∠ C = γ = 44.992° = 44°59'33″
We see 63 angle on right lower side of attachment picture in reflection and can prove x = 3.333
But on your diagram base x = 2
What i have done is enlarged x by 0.3 and proven how to find x if x was just one side of the triangle's height.
The triangles even though reflected are identical.
Other info is proven through finding ha and hb heights.
We confirm 4.001 is the hc height of your diagram.
Height: ha = 2.984
Height: hb = 3.16
Height: hc = 4.001

Triangle ABC is transformed to create triangle MNL. 2 triangles have identical side lengths and measures. The second triangle is shifted down and slightly to the right. Which statement is true? The transformation is rigid because corresponding side lengths and angles are congruent. The transformation is rigid because corresponding side lengths are congruent and corresponding angles are not congruent. The transformation is nonrigid because the two triangles have different names. The transformation is nonrigid because the three sides and the three angles in each triangle have different measures.
Answers

Answer:
The transformation is rigid because corresponding side lengths and angles are congruent
Step-by-step explanation:
The problem statement tells you angles and side lengths are unchanged, so any answer choice contradicting that can be rejected.
Whether a transformation is rigid or not has nothing to do with naming, so you can reject the "different names" answer choice.
The true statement is ...
The transformation is rigid because corresponding side lengths and angles are congruent

area of the resulting cube is multiplied by 4 and the volume is multiplied by 8. Does this
claim make sense?
(select)
make sense.
Answers
Answer:Yes
Step-by-step explanation:
Given
Suppose side length of cube is a
If we dilate the cube using a scale factor of 2
Side length becomes 2a
and the surface area becomes [tex]=6(\text{side length})^2[/tex]
Surface area[tex]=6(2a)^2[/tex]
Surface area[tex]=4\times 6(a)^2[/tex]
Thus surface area multiplied by a factor of 4
Now for volume
[tex]V=(\text{side length })^3[/tex]
[tex]V=(2a)^3[/tex]
[tex]V=8(a^3)[/tex]
Therefore volume is multiplied by a factor of 8
Therefore the above statements make sense

What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
The quadratic equation is given below.
f(x) = x² + 2x - 3
Then the factor of the quadratic equation will be
f(x) = x² + 2x - 3
f(x) = x² + 3x - x - 3
f(x) = x(x + 3) - 1(x + 3)
f(x) = (x + 3)(x - 1)
The zeroes of the function will be
f(x) = 0
(x + 3)(x - 1) = 0
x = 1, -3
Then the zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.

Khan academy told me
The yearly percent change in the mass of the sample will be 81.06%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred.
A sample of a mysterious chemical substance naturally gains mass over time.
The relationship between the elapsed time t, in years, since the mass of the sample, M(t), in grams, was initially measured is modeled by the following function:
[tex]\rm M(t) = (1.16)^{4t+3}[/tex]
The yearly percent change in the mass of the sample will be
At t = 0, we have
M(0) = (1.16)³ = 1.561
At t = 1, we have
M(1) = (1.16)⁷ = 2.826
Then the percentage will be
P = [(2.826 – 1.561) / 1.561] x 100
P = 0.8106 x 100
P = 81.06%
