Answer:
A factor is a number that when its multiplied with another number, gives a product of a given number. Example: The factors of 21 are 7,3,1 and 21. A multiple is a number that can be divided by another number a certain amount of times evenly (without a remainder). Example: Some multiples of 4 are: 8, 12, 16, and 20.
Step-by-step explanation:
✧ 
- Set up an equation and solve for x :
⋆
[ Exterior angle is always equal to the sum of two non - adjacent interior angles ]
~Remove the unnecessary brackets
⟶ 
~Add the like terms : 2x ° & 3x°
⟶ 
~Move 4x to right hand side and change it's sign
~Similarly move 12 to left hand side and change it's sign
⟶ 
⟶ 
⟶ 
- Now , Substituting the value of x in (4x+9)° [ Exterior angle ]

Step-by-step explanation:
Answer:
4000 feet
Step-by-step explanation:
GIVEN: An airplane is flying at an elevation of
and lands on an airstrip
below sea level.
TO FIND: What is the difference between these two elevation.
SOLUTION:
Elevation of airplane while flying 
As airstrip is below sea level,
Elevation airplane while on airstrip 
Difference between elevations 



Hence difference between elevations is 4000 feet.
Answer:
- equation: 1/t = 1/8 + 1/6
- time: 3.43 hours
Explanation:
1) Working speed of Cody: 1 project / 8 hours
2) Working speed of Kaitlyn: 1 project / 6 hours
3) Joint working speed = working speed of Cody + working speed of Kaitlyn
⇒ 1 project / t = 1 project / 8 hours + 1 project / 6 hours
1 / t = 1 / 8 + 1 / 6
That is the equation to solve.
4) Solution of the equation.
1/t = [3 + 4] / 24
1/t = 7/24
⇒ t = 24/7 ≈ 3.43 hours
