So we know this expression:

7x^2 + 2x.

And we know x = 3.

(7*3)^2 + (2*3)

21^2 + 6.

441 + 6

447

Answer:

±sqrt(T*L/m)=v

Step-by-step explanation:

T=mv^2/L

We want to solve the equation for v

Multiply each side by L

T*L=mv^2/L *L

T*L=mv^2

Divide each side by m

TL/m=mv^2/m

T*L/m=v^2

Take the square root of each side

±sqrt(T*L/m)=sqrt(v^2)

±sqrt(T*L/m)=v

Perform the following calculations without rewriting the numbers in decimal form.

RSB [31]

Answer:

Answer will be $140\times 10^{13}$

Step-by-step explanation:

We have to perform the calculation $(1.42\times 10^{15}-2\times 10^{13})$ without changing into decimal

$1.42\times 10^{15}$ can be written as $142\times 10^{13}$

So $1.42\times 10^{15}-2\times 10^{13}=(142\times 10^{13}-2\times 10^{13})$

Now taking $10^{13}$ common

$10^{13}(142-23)=140\times 10^{13}$
