Mathematics
1 answer:
Xelga [282]2 years ago
3 0

Answer:

1. x + 34

2. 2x - 12

3. x - 16

4. x + 45

5. 23 - x

6. 6(x - 7)

7. 78 - 4x

8. 4x + 10

9. 3x + 2

10. x(13 - x)

Step-by-step explanation:

For problems like this in the future, pay attention to the order of words, and how they go together! For example- "the difference of 23 and a number" means to subtract a number from 23, whereas "the difference of a number and 23" would mean to subtract 23 from the number. Words like "increase" and "sum" both mean addition; "product" and "times" both mean multiplication; "difference" and "less" mean subtraction. Just keep these in mind (and watch for context)!

I hope this helped! :)

Help Asap! I have 30 minutes! 30 Points!
Vladimir79 [104]
(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50

10x²  - 45x + 50
 

5( 2x² - 9x + 10)

     2x           -5 
      x             -2

5(2x - 5)(x -2)

make each equal to 0
2x - 5 = 0
x - 2 = 0

2x - 5 = 0                        x - 2 = 0
2x - 5 (+5) = 0                x - 2 (+2) = 0 (+2)
2x = 5                             x  = 2
x = 5/2

x = 5/2 , 2

hope this helps
