X^2+8x+15
= x^2 + 5x + 3x + 15
= x(x+5) + 3(x+5)
= (x+5)(x+3)
Answer:16777216
Step-by-step explanation:
One method that I use often is to bounce the decimal point over and multiply by 2. ex/ total is 23.52, bounce the decimal between the 2 and 3 to get 2.30 then multiply by 2 giving you 4.60.
or take the total 23.52 and multiply it by .20 which will give you 4.70
Here’s a pic of my work, it shows that the numbers 2,7,0 repeat.
Hope this helps!! :)
