Answer:
Area= 2(x^2 + 4)
Perímetro=6x + 8
Step-by-step explanation:
Ancho = x
Longitud = 2x + 4
Area= ancho × longitud
Area= x × 2x + 4
Area= 2x^2 + 4
Area= 2(x^2 + 4)
Perímetro= ancho+ancho+longitud+longitud
Perímetro=2ancho + 2longitud
Perímetro=2(x) + 2(2x+4)
Perímetro=2x + 4x + 8
Perímetro=6x + 8
Answer:
No they don't show direct variation because if you get y alone, the equation you get is in slope intercept form instead of direct variation.
Step-by-step explanation
direct variation: y=kx
y-x=4
+x +x
y= 4+x
Not Direct Variation
