I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
A is correct.
If the two shorter sides squared and added together, equals the longer side squared, then it is a right triangle.
Answer:14 m
Step-by-step explanation:
Dada
larga 
superficie 
Suponga que el ancho es w
La superficie está dada por el producto de la longitud y la anchura.

Por lo tanto, el ancho es de 14 m.
Step-by-step explanation:
L=2B
P=2(L+B)
48=2(2B+B)
48=2(3B)
48=6B
B=8yd
L=2*8
=16yd
Answer:
3rd one. The general form of a circle is set equal to the radius squared. So right side is 4 then plug in values until true.
