Answer:

Step-by-step explanation:

(-2y^2-11y-7)-(-9y^2-5y+10) (firstly, we remove the brackets)

-2y^2 - 11y - 7 + 9y^2 + 5y - 10

= (-2y^2 + 9y^2) + (-11y + 5y) + (-7 - 10)

= (7y²) + (-6y) + (-17)

Answer:

Step-by-step explanation:

The relationship that exists between the length of the hypotenuse and the length of the legs is that the sum of both of the legs lengths squared is equal to the hypotenuse length's squared or in other words, the Pythagorean theorem.

$6^{2} +8^{2} =10^{2}$
