Para encontrar el p<span>erímetro tienes que anadir 3.8, 4 veces o mulltiplicar por 4 </span><span>3.8 + 3.8 + 3.8 + 3.8 = 15.2 </span>3.8 x 4 = 15.2 15.2 es tu respuesta
Para encontrar el area multiplica 3.8 por 3.8 3.8 x 3.8 = 14.44 14.44 es tu area
The x-intercepts are the values of x for which f(x) = 0. x^2 + 4 = 0 x^2 = -4 x= ±√(-4), which are not real numbers. f(x) does not have an x-intercept.
