Speed = Distance / Time
Distance = 5t^4 - 10t^2+6
Time = t+2
Now:
5t^4 - 10t^2 + 6 | t+2
-5t^4 -10t^3 5t^3 - 10t^2 + 10t - 20
\\\\\ -10t^3-10t^2+6
+10t^3+20t^2
\\\\\\\ 10t^2+6
-10t^2-20t
\\\\\ -20t+6
+20t+40
\\\\\ 46

Answer:
answer is 142
Step-by-step explanation:
True. maths is applied in every day life for instance in science and accounting and as well as when daily with money
0.2(6x+1)/3.6=0.5x/9
Solution
(1.2x + 0.2)/3.6 = 0.5x/9
Cross multiplying, we get
9(1.2x + 0.2) = 3.6 * 0.5x
10.8x + 1.8 = 1.8x
10.8x - 1,8x = -1.8
9x = -1.8
Dividing both sides by 9, we get
x = - 0.2
That's the answer.
Thank you.
