Use T and J as names.

T=2x
J=3T  but T=2x, so
 J=3(2x) = 6x
J=6x

(3z+1)(4z+2) simplify
Lorico [155]

You can FOIL (First, Outside, Inside, Last)

(3z+1)(4z+2)

First

(3z+1)(4z+2)

3z * 4z

12z^{2}

Outside

(3z+1)(4z+2)

3z * 2

6z

Inside

(3z+1)(4z+2)

4z * 1

4z

Last

(3z+1)(4z+2)

2*1

2

Combine all the products of FOIL together

12z^{2} + 6z + 4z + 2

Combine like terms

12z^{2} + 10z + 2

Hope this helped!

The density of a fish tank is 0.3 fish over feet cubed. There are 15 fish in the tank. What is the volume of the tank?
ale4655 [162]
Since Density = mass/ volume (d = m / v), and assuming the 15 fish weigh 1 gram each - if weight of each fish isn't given -  (making that a total of 15 grams), 

D = m / v
0.3 = 15 / v 
v = 15 / 0.3 = 50 ft cubed

Hope this answers your question correctly :)

Add. <br> (−2+6x^3−3x^2)+(4x^3−5+x^2)
Gemiola [76]

Answer:

10x^3 - 2x^2 -7

Step-by-step explanation:

To subtract polynomials, you want to subtract the biggest exponent from the first polynomial to the second

so 6x^3 + 4x^3 and that would be 10x^3

then -3x^2 + x^2 and the negative is larger so it would be -2x^2

and finally -2 + -5 and that is -7

hope this helps! :)
