Find the sum of 5m + 3n + p, -5p + 3n, and 2n - m.
-4m + 8n - 4p
4m + 8n + 4p
4m - 8n - 4p
4m + 8n - 4p

The sum of the expression 5m + 3n + p, -5p + 3n, and 2n - m is 4m + 8n - 4p .

Step-by-step explanation:

As given the expression

5m + 3n + p, -5p + 3n, and 2n - m.

Now adding the above expression

= 5m + 3n + p - 5p + 3n + 2n - m

= 5m -m + 3n + 3n +2n -5p + p

= 4m + 8n - 4p

Therefore the sum of the expression 5m + 3n + p, -5p + 3n, and 2n - m is 4m + 8n - 4p .

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
