Answer:
x = 2
All sides have a measurement of 6.
Step-by-step explanation:
ΔRTS is equilateral. This means that all the sides are equal to each other, as well as the angles being equal as well.
We can set two sides equal to each other to solve for 'x'.
I used ST and RS.
[tex]3x = 2x +2\\\rule{150}{0.5}\\3x - 2x = 2x + 2\\\\\boxed{x = 2}[/tex]
Since we have the value of x, we can plug in 'x' in one of the sides and evaluate.
==========================
[tex]ST =3x\\\rule{105}{0.5}\\ST=3(2)\\\\ST=\boxed{6}[/tex]
==========================
Since the sides are equal in a equilateral triangle, all the sides have the measurement of 6.
Hope this helps you.

We can find all the roots by factoring each polynomials.
Case A :
A = 2x^4 + x^3 + 5x^2 + 4x - 12
1 is an obvious Root of this polynomial :
2 * 1^4 + 1^3 + 5*1^2 + 4*1 - 12 = 12 - 12 = 0
Thus we have A= (2x^3+3x^2+8x+12)(x-1)
Lets go further now by factoring 2x^3 + 3x^2 + 8x + 12
We can simply group them :
(2x^3 + 3x^2) + (8x + 12) =
x²(2x+3) + 4(2x + 3) =
(2x+3)(x²+4)
To conclude : A = (2x+3)(x²+4)(x-1)
So the roots are : 1, -3/2, 2i and - 2i
Case B :
B = 2x^4 - x^3 + 5x^2 - 4x - 12
An obvious root here is -1 :
same principle applies, we write B = (2x^3−3x^2+8x−12)(x+1)
Finally B = (x²+4)(2x-3)(x+1)
And the roots are -1, 3/2, 2i and -2i

Evidence points to the Egyptians using gypsum mortar – also known as plaster of Paris – in constructing pyramids during the Pharaonic period. The first Egyptologist to identify this method was Alfred Lucas in 1926.

36
3a
12a2
Answer:
Think the answer is 3a. Hope that helped.
Since 3a is common to both factors, hence the GCF of the expressions is 3a
Greatest common factorThis is the greatest value that can divide the given values without leaving remainder.
Given the following expressions 12a and 9a^2
Find the factors
12a = 3 * 4 * a
9a^2 = 3 * 3 * a * a
Since 3a is common to both factors, hence the GCF of the expressions is 3a

What is the matrix?A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The element in a matrix, such as M, refers to the i-th row and j-th column element.
here, we have,
The matrices are given below.

now, we get,
The product of the matrices will be

Which parachute has a slower descent: a red parachute that falls 10 feet in 4 sec or a blue one that falls 12 feet in 6 sec?
Answer:
The red parachute
Step-by-step explanation:
In order to compare the answers you would need a common time. You could find a number both 6 and 4 factor into, but I decided to take it to one second.
I divided 10 by 4, which is 2.5. Then I took 12 and divided it by 6, which is 2. 2.5 seconds is a longer time than 2 seconds. So the red paachute has a slower decent.

solution of the equation 2x+1=x+3
a. 3
b. 1
c. 2
d. 4
Answer:
C. x = 2
Step-by-step explanation:
2x + 1 = x + 3
subtract the x from both sides so
2x + 1 = x + 3
-x -x
when we subtract the x we are left with x + 1 = 3
since we want x alone we have to subtract 1 from both sides so
x + 1 = 3
-1 -1
3 - 1 = 2 so
x = 2
Now, determine whether the relationship between the two triangles you found in the first task is true for any two triangles. For any line, if you draw two right triangles using the line as the hypotenuse, can the triangles be congruent? Why or why not? Do they have to be congruent? Why or why not?
Answer:
They are not congruent based on the drawing. I don't know what they mean by "do they have to be congruent?", as they don't have to be congruent unless the teacher is asking for them to be congruent.
Step-by-step explanation:
Congruency in geometry is defined as identical in form, meaning that it must follow CPCTC (and can be proven in many different ways).
In the case of the given triangles they are not congruent, as DE and AD do not share congruency with BA and CB, respectively. At best, the two given triangles are similar triangles, as ΔADE is a 2x scale factor of ΔCBA.
I am not sure what the question about "do they have to be congruent" is for. Obviously they aren't congruent and so they don't have to be? There is nothing that states they have to be congruent. If you are aiming for congruency, lines AB & CB's measurements would simply have to match that of ED & AD, respectively.

Answer:
The relationship we found is that:
The triangles have same vertical/horizontal segment ratio or slope.But this doesn't indicate the triangles are congruent. They have different side lengths which makes them similar but not congruent.
They can be congruent if corresponding sides are of same length.
