6.50 to the nearest hundredth (4.685 & 1.815)
the product of 5x4 because 5x4=20 and 5+4=9
5 and 4. 5x4=20 (product) 5+4=9 (sum)
Yes. Here is an example: P1 = 5x4 + 3x3; P2 = -5x4 -2
The sum of 3 plus 4 is 7.
The answer will be 21x + 1

Yes. Here is an example: P1 = 5x4 + 3x3; P2 = -5x4 -2
You should look for two numbers whose product is 40, and whose sum is 13. Experimenting a little (trying different pairs of factors for 40), you can quickly realize that this works for 8 and 5. Therefore, x2 + 13x + 40 = (x + 8) (x + 5)
12x2+13x-35 = (4x-5)(3x+7) 12x2 + 13x- 35 let's find two factors of -420 (12*-35) whose sum is 13, which are 28 and -15 (12x + 28)(12x - 15) now simplify by 4 and 3 (3x + 7)(4x - 5)
When you check an answer by using it in another sum e.g2x+7=13x=3substitute to second-4x+6=18x=3 which is correct
The sum answer = 3440
The sum is 1511.
The sum of 7 plus 71 is 77.
The sum of 75 plus 5 is 80.
