Use the distributive property to remove the parentheses. −9(w−3y+6)

1 answer:

6 0

-9w + 27y - 54
If that's all you need - You're just multiplying 9 with each number in the parenthesis! I hope all is well, and you pass! Good luck, rockstar. (:

AH the second question

Degger [83]

Answer:

ii. 55 degrees.

Step-by-step explanation:

(ii)

Consider the quadrilateral ABCD.

Angle n = 180 - 96 = 84 degrees ( opposite angles of a cyclic quadrilateral are supplementary).

Consider triangle ABC: the 3 angles are supplementary, so

m < j = 180 - 84 - 41

= 55 degrees.

Answer:

$y = e^{x^2 - 3x}\\\\\\Let \ u = x^2 - 3x\\\\y = e^u\\\\\frac{dy}{du} = e^u\\\\\frac{du}{dx} = 2x - 3\\\\y' = \frac{dy}{dx} = \frac{dy}{du} *\frac{du}{dx} = e^u * (2x -3)\\\\Substitute \ u = x^2 -3\\\\y' = (2x -3)e^{x^2-3x}\\\\option A$
