area is side x side

2sqrt3  x   2 sqrt3 = 4 (3) = 12      ( units²  )

sqrt(6)+sqrt(7) = 5.0952410538477687      So    '5' would be the biggest integer less than

find the slope     (y1-y2)/(x1-x2)   this is slope  'm'

then

y = mx + b    sub in one of the x,y points to find  ' b'

'

then you line is  y = mx + b

starts with 24  

   24   -   1/4 (24) - 1/3(24) =   how many he has left ........

Cats are 8 out of (8+12) =  20       8/20 * 36 = 14.4 cats       yup    14.4 cats

8 - sqrt 3   would be the other root      x^2 -16x+61

We started this here.....gave you most of the answers....did you try to get further?  Or are you just trying to get answers without any effort other than posting?

x+y = 4        can only be    1 3     or   2  2    which would not satisfy the next equation

x^2 + y^2 = 28               Are you sure they are both positive?

Hassan   4p+2h=18.00

Aviv         5p+5h=36.25          two equations and two unknowns.....solve for h and p

                                               multiply first equation by - 1.25 to get

               -5p -2.5h = -22.5      and add this to the second equation to get

                     2.5 h = 13.75

                          h = 5.50

then sub into one of the equations

    5p + 5(5.5) = 36.25      p =1.75  

Vertex form    y = a (x-h)^2 + k

y = 7x^2 + 14x + 4  =   7 (x^2 + 2x)    + 4     'complete the square'

                                =  7 (x+1)^2       -7 + 4

                                = 7 (x+1)^2    -3
