4th term is   1 out of (4+1)  = 1/5      sixth term is   4/5

1/5 x r x r = 4/5

r^2 = 4    r =2

1st and third terms     x   +   x * r * r  = 40

                                    x + 4x = 40

                                     x = 8 = first term

5th term   8 r^4 = 8 * 16 = 128              

I suppose 6?

1 x 2 x 3 = 6

2 x 3 x 4

3 x 4 x 5

4 5 6

Area of a right triangle   =  1/2  b h

  you have 3 triangles of b,h            1)  3.5  x 9       2)   2 x 2     3)  2x5

      and add a small square that is  2 x 2

3x^4+2x-1+h(x)=5x^2-6x-1      subtract  3x^4 + 2x -1   from both sides

h(x)  = -3x^4 + 5x^2 - 8x

tan x  = opposite / adjacent = 3/7

arctan(3/7) = x  = ~~23^o

No, you can't    

4 L + 4 A = 10     is basically the same equation as

2 L  + 2 A  = 5     (just divided by 2)

Perimeter = 8 + 8   + w + w   = 24

                                    soooo   w = 4

ratio   w/l =    4/8 = 1/2

B = brandon distance

P = pat distance = 545 - B

B/100     +   (545-B) / 90  = 5.75         solve for B   = Brandon's distance ....then   P = 545 - B

Slope , m =  (y1-y2) / (x1-x2)    =  (10- -2) / ( 6-4) = 6

y = mx+b     becomes   y = 6x+b    sub in oneof the points to calc 'b'

10 = 6(6) + b    b = - 26

y = 6x-26

There wil be   a  15 x^4   when the first terms are multiplied.....rules no choices out

   there will be a -15   when the constants are multiplied   so it is B or D

     when the x tems are multiplied by the constants  there will be a - 10x  and a - 12x = - 22x    so answer  B
