Assume that the nullspace of L = {0}. Explain how it follows that the nullspace of M is {0}? How does it follow that the equation L(X) = Y has at least one solution for all Y ∈  ? Hint: First explain why M is an n × n matrix.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
