The mathematical expression 2 v means: 2 is an element of set w 2 is a subset of set w 2 is an element of set v none of the above

If you wanted to write 2V, then 2 is a coefficient of V, and the answer will be "none of the above"

now, suppose that V is a subset of W, or V⊂W

if the expression says 2⊂V, then 2 is a subset of V and a subset of W.

if the expression says 2 ∈ V then 2 is a element of V and a element of W

if 2 ⊂ W, then 2 is an subset of W, but not necessarily an subset of V

if 2 ∈ W, then 2 is an element of W, but not necessarily an element of V.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
