Mathematics
1 answer:
OverLord2011 [107]3 years ago
8 0

\bf Step-by-step~explanation:

\bf Step~1:

To solve this, we have to simplify these numbers by adding like terms.

42x^2+34-8-12\\\\(34-8=26, 26-12=14)\\\\42x^2+14\\

\bf Step~2:

Next, we factor our expression. To do so, we look for the greatest common factor of 42 and 14, which is 14. We know that because 42 divided by 14 is 3.

\frac{42}{14} =3

\boxed{ \bf Our~final~answer: 14(3x^2 + 1)}

Suppose PV =NRT, where P=8, V=2X, N=2 and R=2X.you are given X=3. Solve for T
FromTheMoon [43]

Answer:  T = 4

Step-by-step explanation:

1. Write all the variables down

P = 8  V = 2X  N = 2  R = 2X  X = 3

2. Since you know that X = 3 substitute it in to find V and R

V = 2X = 2(3) = 6

R = 2X = 2(3) = 6

3. Find PV

PV = P x V

     = 8 x 6

     = 48

4. Find NRT

NRT = N x R x T

       = 2 x 6 x T

       = 12 x T

       = 12T

5. Find T

PV = NRT

48 = 12T

12T = 48

divide both sides by 12

  T = 48 ÷ 12

  T = 4
