I think it is both! I might be wrong.
The answer would be B. 8m.,
because if the base is 8, the height would be 6+8=14, and 14 x 8=112 x 1/2=56 m^2.
we know that
triangles BCD and ACE are similar
so, their ratios of sides must be equal
Calculation of y:
we can see that
AC=AB+BC
AC=y+3
CE=CD+DE
CE=4+6
CE=10
now, we can plug values
now, we can solve for y
Calculation of AC:
we know that
AC=y+3
we can plug y
and we get

Answer:
12
Step-by-step explanation:
10x-11+3x-2+3x+1=180
16x-12=180
16x=192
x=12
LC=1
Step-by-step explanation:
f(x)=x^2-8x-4
=(1)x^2-8x-4
