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.

The Oakville High School Marching Band sold gift wrap to earn money for a band trip. Solid color gift wrap sells for $3.50 per r
GalinKa [24]

Let, number of solid color gift sold is x and printed gift wrap is y.

Also, number of printed paper sold , 325.

Expressing, it in mathematical equation :

y = 325    ....... 1)

Also, The band needs to earn $2,500 for an upcoming competition.

So ,

3.5x + 5y = 2500    ....... 2)

Solving equation 1 and 2 :

3.5x + 5(325) = 2500

3.5x = 2500 - 1625

3.5x = 875

x = 250

Therefore, number of solid paper they must sell is 250.

Hence, this is the required solution.
