Step-by-step explanation:
multiply by the factor for each one to get a bigger picture
Answer:
2×25
THE ANSWER TO IT WOULD BE 50
Step-by-step explanation:
Volume = length * height * width
= 4 qrt3 + 3 sqrt6 * w
= 12 sqrt18 w
let w = 2 sqrt50 then volume = 2*12 * sqrt 18*50 = 24*30 so this is rational
let w = 4 sqt 12 the v = 48 sqrt12 * sqrt 18 = 48 sqrt30 which is irrational
C and D are rational
answer is B
1. 950
2. 608
3. 1,976
4. 2,698
5. 1,216
