\fFind the area enclosed between f(a) = 0.4x + 10 and g(@) = x from x = -4 tox = 7.Sketch the region enclosed by the given curves. Decide whether to integrate with respect to a: or y. Then nd the area of the region. y=8+,y=8+%x Sketch the region enclosed by a = 2y and a + y = 1. Decide whether to integrate with respect to x or y. Then find the area of the region
