I WILL MARK BRAINLIEST PLEASE HELP !! Determine whether the two triangles are similar.
Answers
The two triangles are similar by SSA similarity. Option B is correct.
What is the triangle?A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.
From the triangle ABC and DEC
The ratio of the sides is;
[tex]\rm \frac{10}{12}= \frac{8}{9.6} \\\\ \frac{5}{6}= \frac{5}{6}[/tex]
One angle c is common in the two triangles.

Determine the value of K that will cause f(x)=Kx^2+4x-3 to intersect the line g(x)=2x-7 at 2 points
Answers
By using the definition of second order polynomials and the discriminant from quadratic formula, we conclude that the values of k must be less than 1/4.
How to determine the value of k such that a line intersects a quadratic equation
In this question we must determine the set of values of k such that the function g(x), a linear function, intersects a quadratic function f(x) at two points. In this case, we must solve the following second order polynomial:
k · x² + 4 · x - 3 - g(x) = 0
k · x² + 4 · x - 3 - 2 · x + 7 = 0
k · x² + 2 · x + 4 = 0
In this case, the discriminant of the equation described above must be positive:
2² - 4 · k · 4 > 0
4 - 16 · k > 0
4 > 16 · k
16 · k < 4
k < 1/4
By using the definition of second order polynomials and the discriminant from quadratic formula, we conclude that the values of k must be less than 1/4.

By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.
The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).
Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).

Answers
Answer:
AB = 4
BC = 4
AC = 8
Step-by-step explanation:
Given, B is the midpoint of AC which means it divided the AC into two equal parts. Using this information we can write the following equation:
5x - 6 = 2x add 6 to both sides
5x = 2x + 6 subtract 2x from both sides
3x = 6 divide both sides by 3
x = 2 to find the length of AB, AC, and BC replace x with 2
AB = 5*2 - 6
BC = 2*2
AC = 8 (sum of AB and BC)

The volume of a rectangular prism is given by the expression 2x^4+2x^3-4x^2-4x. Write the volume as the product its dimensions. Remember, V = lwh.
Answers
=========================================================
Explanation:
First factor out the GCF 2x
2x^4+2x^3-4x^2-4x
2x*x^3+2x*x^2-2x*2x-2x*2
2x(x^3 + x^2 - 2x - 2)
Then let's factor the expression inside the parenthesis using the factor by grouping method
x^3 + x^2 - 2x - 2
(x^3 + x^2) + (- 2x - 2)
x^2(x + 1) - 2(x + 1)
(x^2 - 2)(x+1)
We see that x^3 + x^2 - 2x - 2 factors to (x^2-2)(x+1)
Overall, the original expression fully factors to 2x(x^2-2)(x+1)
length = 2x
width = x^2-2
height = x+1
The order of length, width, and height doesn't matter.
The volume as the product its dimensions 2x*( x²-2)*(x+1).
What is Volume?Volume is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given:
volume of a rectangular prism is given by the expression 2x^4+2x³-4x²-4x
=2x*x^3+2x*x^2-2x*2x-2x*2
=2x(x³ + x² - 2x - 2)
Now, we get the factor 2x(x³ + x² - 2x - 2).
Keeping aside 2x we will now focus on (x³ + x² - 2x - 2)
We already get the one factor 2x and now using (x³ + x² - 2x - 2) to get the other two factors.
Now solving x³ + x² - 2x - 2
=(x³ + x²) + (- 2x - 2)
= x²(x + 1) - 2(x + 1)
=( x² - 2)(x+1)
Now we get the two factors ( x² - 2)(x+1).
The expression for volume as the product its dimensions is 2x*( x²-2)*(x+1)
Hence, volume as the product its dimensions is 2x*( x²-2)*(x+1).
