(4p + 5)(p + 1) = 0

ale4655 [162]

Answer:

$4p {}^{2} + 4p \: + 5p + 5$

$= )4p {}^{2} + 9p + 5$

$= )4p {}^{2} + (5 + 4)p \: + 5$

$= )4p {}^{2} + 4p \: + 5p \: + 5$

$= )4p(p \: + 1) + 5(p \: + 1)$

p = - 1 , -5/4

Answer:

Ques 1) 1440°

Ques 2) 4000

Ques 3) 33

Step-by-step explanation:

Ques 1)

The sum of the measures of the angles in degrees of a polygon with 'n' sides is given by: 180×(n - 2).

Now we have to find the sum of the measures the angles of a polygon with 10 sides.

i.e. n=10

Hence the value of the expression 180×(n-2) when n=10 is given by:

180×(10-2)=180×8=1440.

Hence, the sum of measure of the angles of a polygon with 10 sides is: 1440°.

Ques 2)

The Expression 500v gives the number of points a player earns for completing v voyages in video game.

We are asked to find the number of points earned for completing 8 voyages.

i.e. v=8 the value of 500v will be 500×8=4000.

Hence, 4000 points are earned for completing 8 voyages.

Ques 3)

we have to find the value of the question as given in the figure:

7x+y+16 for x=2 and y=3.

Hence, we find the value of the expression:

7×2+3+16=33.

Hence, the value of the expression is 33.
