Answer:

Always.

Step-by-step explanation:

That is the reason why when you are trying to calculate the area of a triangle you do the base x height divided by two or in half. If you printed out the triangle twice then cut it out and put the two together it would be a rectangle.

Always, let’s put an example that the base and the height is 6 and 8 and when you try to get the area with those numbers on a rectangle is 48 and the half of 48 is 24 and when trying to get the area of a triangle with those same numbers you get 24 so it’s always.

yarga [219]

The correct answer is A) 2/5

That is because the probability of it is equal to the number of numbers larger than 6 divided by 10, which is 4/10, or 2/5 when reduced.

Solve: let f(x)=2x-1 and g(x)=x^2-4. find g(f(x))

Stella [2.4K]

<h3>Answer: g(f(x)) = 4x^2 - 4x - 3</h3>

Work Shown:

g(x) = x^2 - 4

g(f(x)) = ( f(x) )^2 - 4

g(f(x)) = ( 2x-1 )^2 - 4

g(f(x)) = (2x-1)(2x-1) - 4

g(f(x)) = 4x^2-2x-2x+1 - 4

g(f(x)) = 4x^2 - 4x - 3

Answer:

Option 3rd is correct

No,

she should have added $6^2$ and $8^2$ and compared that to $10^2$

Step-by-step explanation:

In a right angle triangle, we use Pythagorean theorem.

Pythagorean theorem states that

the sum of the squares of two sides must equal the square of the third side(the side facing the right angle).

i.e, $\text{Hypotenuse side}^2=\text{sum of the square of two side}$

Given a triangle with side lengths 6, 10, and 8.

If we square all the given sides, we get;

$6^2 = 36$ ,

$8^2 = 64$

$10^2=100$

It can be seen that the sum of 36 and 64 is 100

⇒ $6^2+8^2 = 10^2$

which satisfies the Pythagorean theorem.

⇒ The triangle is right-angled with the side lengths 6 units and 8 units forming the right angle and the side length 10 units being the hypotenuse.

Therefore, her answer is incorrect, she should have added $6^2$ and $8^2$ and compared that to $10^2$
