For a square, with a length of 8x-2, the height must be the same in order for this to be a "square". The area of a square is the height multiplied by the length, so (8x-2)^2 will be your answer. Simplified it will be 64x^2 - 16x + 4.
Answer:
Step-by-step explanation:
Given equation:

Solving for 
Combining like terms on both sides.


Adding
both sides to get
terms on one side.


Adding 12 both sides to isolate
on one side.


Dividing both sides by 8.

∴
(Answer)
Answer:
8n
Step-by-step explanation:
8n is the factor of both 8 and n. in the following question. Factor ⇒ If a number, that use to divide another number and we get zero as a remainder, the number is called the factor of another number.
#8. The answer would be 189. The LCM (least common multiple) of 2 or more numbers, is the multiple that each number has in common with one another. Here are the multiples of both numbers up to 189, to show 189 is the answer.
- 21: 21, 42, 63, 84, 105, 126, 147, 168, 189
- 27: 27, 54, 81, 108, 135, 162, 189
#9. The answer would be 41. Prime numbers are numbers that only have 2 favtors (1 and itself). Since 41 is only divisible by 1 and itself, without the answer being a decimal, it is a prime number.
#10. The answer would be 6. The GCF (greatest common factor) of 2 or more numbers, is the largest factor that each number has in common with one another. Here are the factors of both numbers, to show 6 is the answer.
- 30: 1, 2, 3, 5, 6, 10, 15, 30.
- 48: 1, 2, 3, 4, 6, 8, 12, 24, 48.
I hope this helps!
