Answer: x = -2

Step-by-step explanation:

Given:

Perimeter = 50 cm

=> 2 (2x+15)+ 2(3x+20) =50

=> 4x+30+6x+40=50

=> 10x= -20

=> x= -20/10

=> x = -2

Answer:

The top graph

Solutions:

-2

0

Step-by-step explanation:

The given quadratic function in factored form is

f(x) =  - (x + 2)(x - 2)

This is a parabola that has x-intercepts at (-2,0) and (2,0)

This parabola opens downward because the leading coefficient is less than 1.

The second function is

g(x) = 2 |x  + 2|

This is an absolute value function with vertex at (-2,0).

Therefore the graph that shows the solution to f(x)=g(x) is the top graph.

Hence the solution is x=-2,x=0
