P^2=mx/t-t^2x make x the subject

belka [17]

Answer:

$x=\frac{P^2t}{(m-t^3)}$

Step-by-step explanation:

$P^2=\frac{mx}{t} -t^2x\\\\P^2+t^2x=\frac{mx}{t}\\\\t(P^2+t^2x)=mx\\\\P^2t+t^3x=mx\\\\P^2t=mx -t^3x\\\\P^2t=x(m-t^3)\\\\\frac{P^2t}{(m-t^3)} =\frac{x(m-t^3)}{(m-t^3)} \\\\\frac{P^2t}{(m-t^3)}=x$

Solve the perimeter for an isosceles triangle, p=2a+b, for a.

Snowcat [4.5K]

Answer:

a= 1/2p-b

Step-by-step explanation:

p=2a+b

divide by 2 on both sides

1/2 p = a+b

subtract b from both sides

1/2 p - b = a

flip equation (not needed, just personal preference)

a= 1/2p-b

(Sorry if I didn't understand well enough and got it wrong)
