Elimination because u could multiply the second equation by -3 which would cancel the x and allow you to solve for y and then everntually x but yea elimination is the best method
Substitute -3 to x
(-3)^2 + 4(-3) + 1
9 - 12 + 1
= -2
Take DEBC a parralelogram
Parralel sides are DE and BC
THEREFORE,
1/2*(a+b)*h
1/2*(6+15)*h
1/2*(21)*h=0
10.5*h=0
h=-10.5
The area of the figure is 28 yd^2
What is the question you need answered?!
