5:20

Step-by-step explanation:

reasons

1:sum of all side of triangle is 180 degree(here is 220)

3: try in copy and u will able to solve

4:first of all make 9 cm as shown in figure and draw 15 . finally measure the remaining side.

5: 3y+5y+y=180

9y=180

hence,y=20

Which graph represent the solution set of y=x^2+4x+3 and y=2x+6

Mamont248 [21]

Answer:

solution set are

$(-3,0)$

$(1,8)$

Step-by-step explanation:

we are given system of equation as

$y=x^2+4x+3$

$y=2x+6$

For finding solution set , we can draw graph of both equations

and then we can find intersection point

the intersection point will be our solution set

we get graph as

So, solution set are

$(-3,0)$

$(1,8)$
