2. suppose l : v w is a linear map between n-dimensional vector spaces, and let a be the matrix corresponding to l with respect to bases b of v and c of w. (a) prove that if rank(a) n, then l is an isomorphism. (b) prove that if 0 is an eigenvalue of l, then l is not surjective.

Th perimeter of a rectangular garden is 150 feet. the length is 50 feet longer than the width, w. which equation could be used to calculate the width of the garden? a.) 2w+ 2(w-50) =150 b.) 2w+50 + 2w =150 c.) 2(w+50) + w =150 d.) 2w+ 2(w + 50) = 150 need asap. will give brainliest !
