Let u, v, w be vectors in 3− space. Prove the following

< u ∧ v,(v ∧ w) ∧ (w ∧ u) >= square of det(u, v, w)

^=cross product

can you solve it ?

b

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

5.7622

step-by-step explanation:

the ten thousandths place is the 2. you round it up if, that number in whatever place is 5 or higher.
