Factor 200t+8t^3-80t^2

valina [46]

Answer:

8t(t - 5)^2

Step-by-step explanation:

I would immediately rearrange these terms in descending order by powers of t:

8t^3 - 80t^2 + 200t

Then I'd factor out 8t:

8t(t^2 - 10 t + 25).

Finally, I'd factor the quadratic t^2 - 10 t + 25:

(t - 5)^2

and so 200t+8t^3-80t^2 in factored form is 8t(t - 5)^2.

Answer:

T = 3.5 hours

Step-by-step explanation:

this is a rate problem.

an experienced surveyor takes 7 hours to survey a roadbed

an apprentice surveyor takes 9 hours to survey a roadbed

the rate of the experienced surveyor = $\frac{1}{7}$

the rate of the apprentice surveyor = $\frac{1}{9}$

if the two work together , $\frac{1}{T} =\frac{1}{7} +\frac{1}{9}$

T = $\frac{56}{16}$

T = 3.5 hours
