Step-by-step explanation:

2x^2+8x+6

Factor out a 2

2(x^2 +4x+3)

Factor in side the parentheses

What multiply to 3 and adds to 4  (3(1=3  3+1 =4)

Answer:

y=5

x=20 degrees

K= 43 degrees

L=137 degrees

Step-by-step explanation:

aducent angles of parralologram add to 180 degrees

so (6x+17)+ (2x+3)=180

or 6x+17+2x+3=180

so 8x+20=180

and 8x=160

x=20 degrees

opposite sides of parralologram are equal so

6y-13= 32-3y

or 9y=45

and y=5

opposite angles are coonguent so

ang K= 2x+3

so K= 43 degrees

aducent angles of parralologram add to 180 degrees

so ang L+43=180

and L=137 degrees

Answer 5, 6 , and 7 by today please.
kherson [118]

Answer:

Step-by-step explanation:

5. a) ∠1 and ∠2 are remote interior angles of ∠ACD so that means that ∠ACD = ∠1 + ∠2

   b) Because an exterior angle is the sum of its two remote interior angles it makes sense that an exterior angle is greater in measure than either of its remote interior angles.

6. BD = DB  Reflexive property

    ∠3 = ∠5, ∠4 = ∠6  Alt. int. angles

    ΔADB = ΔCDB   ASA

7. AB = BC Def. of midpoint

   ∠1 = ∠2 Given

   ∠BAE = ∠CBD Corresponding angles

   ΔBAE = ΔCBD ASA

    ∠D = ∠E CPCTC

There are 6 diagonals that can be drawn from one vertex of an octagon, true or false.
FinnZ [79.3K]
It's False; an octagon has 8 vertices. When you remove the starting vertex and the two adjacent vertices we're left with 5 possible diagonals
