If x square plus 8x plus q =(x plus k) Square find the value of k and q​
PIT_PIT [208]

Answer:

The value of k is 4 and q is 16.

Step-by-step explanation:

First, you have to expand the brackets by applying :

{(a + b)}^{2}  =  {a}^{2}  + 2ab +  {b}^{2}

{x}^{2}  + 8x + q =  {(x + k)}^{2}

{x}^{2}  + 8x + q =  {x}^{2}  + 2kx +  {k}^{2}

Next, you have to do it by comparison :

{x}^{2}  + 8x + q =  {x}^{2}  + 2kx +  {k}^{2}

by \: comparison

8x = 2kx

8 = 2k

k = 4

q =  {k}^{2}

q =  {4}^{2}

q = 16

The perimeter of the given circle is 25.1 square cm.

Step-by-step explanation:

  • From the given diagram, the radius of the given circle is 4 cm.
  • The perimeter of any given circle is calculated by multiplying 2π with the radius. The radius of this circle is 4 cm and it says π = 3.142
  • The Perimeter for the given circle = 2π × r = 2 × 3.142 × 4 cm = 6.284 × 4 cm = 25.136 cm.                                                       Rounding this off to one decimal 25.136 square cm, the perimeter equals 25.1 square cm.
