If you know that 5*6=30 then you know that the answer will be more than 30. So now you have to just add 6 to the number 30 three more times to get the answer that 8*6=48
The distance from his home to the store is represented by
41x² + 357x - 15.
We know the distance from the store to the library, and the distance from his home to the library. We also know the store is between the two. To find the missing distance, we subtract the two polynomials we have:
(54x² + 310x + 8) - (13x² - 47x + 23)
Combining like terms:
54x² - 13x² = 41x²;
310x -- 47x = 310x + 47x = 357x;
8-23 = -15
This gives us
41x²+357x-15
5x+4 u add -8x and 13x and then -2 +6
Y = -3/8x - 7....add 3/8x from both sides
3/8x + y = -7 ...multiply both sides by 8
3x + 8y = - 56 <==
