Answer:
8 shelves
Step-by-step explanation:
First do 378 divided by 50 then you when you get your answer (with remaining numbers) you add one more book case so 378 divided by 50 is 7 then you have a remainder 28 so add another shelf which is now 8 shelves!
1. (x + 6)(x + -12)
2. (x + 10)(x - 10) = x² - 100
3. (x - 6)(x + 17) = x² + 11x - 102
4. (-x + 8)(x - 5) = -x² + 13x - 40
5. (x + 13)(x + 8) = x² + 21x + 104
6. (x + 2)(x + 7) = x² + 9x + 14
Answer:
(2,5) and (5,8)
Step-by-step explanation:
you can just plug in the numbers to get your answer and if two numbers aren't the same then its not a solution
example: (2,5)
5 = 2 + 3
5 = 5
5 does equal 5 making it a solution because it makes sense right?
example: (4,6)
6 = 4 + 3
6 = 7
this isn't a solution because six doesn't equal 7
