Answer: find the answer in the explanation.

Step-by-step explanation:

To use the Pythagorean theorem to prove if a triangle with the side lengths 7,14,28 is a right triangle, you will square 7 and add it to the square of 14. The square root of the sum will be equal to 28 if it is a right angle triangle. Otherwise, it is not.

(7^2 + 14^2) = 49 + 196

245

Find the square root of 245

Square root = 15.65

Since it is not 24, the triangle is not a right angle triangle.

Given:

The quadratic equation is

$y=6x^2-9x+22$

To find:

The correct application of the quadratic formula.

Solution:

If a quadratic equation is $ax^2+bx+c=0$ , then the quadratic formula is

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

We have,

$y=6x^2-9x+22$

Putting $y=0$ , we get

$6x^2-9x+22=0$

Here, $a=6,b=-9,c=22$ . Using the quadratic formula, we get

$x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}$

The correct application of the quadratic formula is $x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}$ .

Note: The options are not in proper format.

-3(y+2)2-5+6y
Steps
Multiply the numbers: 3 x 2 = 6
= -6(y + 2) - 5 + 6y
Then, expand - 6(y + 2): -6y - 12
= -6y - 12-5 + 6y
Simplify
-6y - 12 - 5 + 6y
= -17
