It’s very simple there’s a couple steps you need to do. Learn the material study it and then remember it
$310 dollars because after it res and decreased it gained $.10 and 100 x 3 is 300 so thats before you calculate how much it rose so .10 x 100 is 10 so add that to 300 and you get 310
The persons above me is correct
Answer:
(x+6)(x+2)(x-5)(x-7)
Step-by-step explanation:
step 1: ((((x4)-(4•(x3)))-72x2)+136x)+420
step 2: ((((x4) - 22x3) - 72x2) + 136x) + 420
step 3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 2 and 6
x2 + 2x + 6x + 12
step 4: Add up the first 2 terms, pulling out like factors :
x • (x+2)
Add up the last 2 terms, pulling out common factors :
6 • (x+2)
step 5: Add up the four terms of step 4 :
(x+6) • (x+2)
Which is the desired factorization
