Answer:
2/5a + 4b + 1/6c
Step-by-step explanation:
- Distribute 1/5 throughout the parentheses (multiply it by each term enclosed in the parentheses) --> this gives you 2/5a -3b + 1/6c + 7b
- Then you just combine like terms to get your answer. In this case, the only like terms you need to combine are -3b and 7b to get -3b
80 feet long because 1x1 1 80x1 80 sooooooooooo that’s your answer!!!
Answer:
16
Step-by-step explanation:
Set up the equation ->
x+32=3x
(you can get this easily by writing the equation down as you read the problem)
--> revisiting x+32=3x
-x on both sides to isolate the number and put the like terms together
We are left with 32=2x
Divide 2 on both sides, and you will get x (his current age) --> x=16

Using the Pythagorean Theorem,
a² + b² = c²
c² = 8² + 8²
c² = 64 + 64
c² = 128
c = √128
c =8√2 (radical form) or 11.31 feet (nearest hundredth)
Answer: 11.31 feet
(1/5)^3 = 1/5 * 1/5 * 1/5 which = 1/125
