What is the value of p in the equation 13p+42=-57+2p

ira [324]

Answer:

p=-9

Step-by-step explanation:

13p+42=-57+2p

Subtract 2p from each side

13p-2p+42=-57+2p-2p

11p +42 = -57

Subtract 42 from each side

11p+42-42=-57-42

11p = -99

Divide each side by 11

11p/11 = -99/11

p = -9

7-4i divided by <br> 2+i <br> how to solve it?

cupoosta [38]

$\cfrac{7-4i}{2+i}\\\\ = \cfrac{(7-4i)(2-i)}{(2+i)(2-i)} \\\\ =\cfrac{14-7i-8i-4}{4+1} \\\\= \cfrac{10-15i}{5} \\\\= \cfrac{5(2-3i)}{5} \\\\=2-3i$

Find the solution of ___ and determine if it is an extraneous solution

Alex

Answer:

x = 14 is an extraneous solution

Step-by-step explanation:

$4\sqrt{x + 2} = -16$

Divide both sides by 4.

$\sqrt{x + 2} = -4$

Square both sides.

$(\sqrt{x + 2})^2 = (-4)^2$

$x + 2 = 16$

$x = 14$

Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.

Check x = 14:

$4\sqrt{x + 2} = -16$

$4\sqrt{14 + 2} = -16$

$4\sqrt{16} = -16$

$4(4) = -16$

$16 = -16$

16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
