Answer:
v = ± 
Step-by-step explanation:
Given
E =
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ± 
Answer:
2 and 6, 1 and 5
Step-by-step explanation:
Point six repeatedly so 0.16666666666... so just put a bar over the six
Multiply the numbers: 3 x 2=6 = 6x + 5 - 12x - 2 x 149x
Next Multiply the numbers 149 x 2 = 298
Then, Group like terms, =-6x-12x-298x+5
Add similar elements -6x-12x-298x=-316x,
and you get -316x+5!
Answer:
3
Step-by-step explanation:
(43-20)-2*5
Step 1: 43- 20= 13
Step 2: 2*5 = 10
