=(3x^3-y^2)^2 [ open it in (a-b)^2 form]
=(3x^3)^2-2.3x^3.y^2+(y^2)^2
=3^2x^3×2-6x^3y^2+y^2×2
=9x^6-6x^3y^2+y^4. ans
-19 and -20
-/375 = 19.3649
So round up and down to the nearest integers and get -19 and -20
Do the i p t interest percentage and time the you add the percentage and interest then you multiply that by your time
Answer:
298000:100
x : 103
cross multiply: 100x=298000 x 103
x=306,940 or 307,000
Step-by-step explanation:
Answer: S = 20 lbs L = 45 lbs. Both answer have been rounded from below
Step-by-step explanation:
L+S = 65 lbs
55L + 65S = 3774 lbs
55L+55S = (65)(55) = 3,575 lbs
10S = 199 lbs
S = 19.99 (round to 20)
L + S = 65
L + 19.99 = 65
L = 45.01 (round to 45)
