e. 2y(y + 3)this is not a quiz it is an assignment that is due tomorrow and I Wil be grateful for anyhelp
Elena-2011 [213]

We need to multiply

-2y(y+3)

We need to use the distributive property to expand this:

a(b+c)=ab+ac

Let's multiply it out using this property, to get our answer:

\begin{gathered} -2y(y+3) \\ =-2y(y)+(-2y)(3) \\ =-2y^2-6y \end{gathered}

Determine the longest side in ΔDEF.
Helen [10]

Option D:

Segment DF

Solution:

Let us first define the relationship between the side and angle in triangle.

<u>Relationship between the side and angle in triangle:</u>

  • The shortest side is always opposite to the smallest interior angle.
  • The largest side is always opposite to the largest interior angle.

To find the largest side in ΔDEF:

Largest angle in ΔDEF is ∠­E = 73°

So, the side opposite to 73° is DF.

Therefore, Option D is the correct answer.

Hence the segment DF is the longest side in the ΔDEF.
