Answer:
4√5
Step-by-step explanation:
2√5 + 3√5 - √5 = 4√5
add up 2 and 3 that's in front of √5 then subtract 1 from it
Jane has 20 pounds and Charlotte has 16 pounds
Let j = amount Jane has and c = amount Charlotte has
j - 2 = c + 2 if Jane gives Charlotte 2 pounds
j + 4 = 2(c - 4) if Charlotte gives Jane 4 pounds
j + 4 = 2c - 8
Subtract equation 1 from equation 3
6 = c - 10
c = 16
j = c + 4 = 20
Answer:
8, 9, 10, 11, 12
Step-by-step explanation:
Consecutive integer problems are often easier to work if you consider average values. Here, the middle of the 5 consecutive integers is their average, which is 50/5 = 10.
This tells you the integer side lengths are 8, 9, <em>10</em>, 11, 12.
