Since one of the roots is  1 - sqrt(2),  another root will be  1 + sqrt(2).

Since one of the roots is  2 + sqrt(7),  another root will be  2 - sqrt(7).

One possible solution is:  ( x - [1 - sqrt(2)] ) · ( x - [1 + sqrt(2)] ) · ( x - [ 2 + sqrt(7) ] ) · ( x - [ 2 - sqrt(7) ] )  =  0

Other solutions can be found by multiplying that solution by an non-zero real number.

Thank you everyone!!!!

The expansion of  (m + n)⁸ 

      =  1m⁰n⁸  +  8m¹n⁷  +  28m²n⁶  +  56m³n⁵  +  70m⁴n⁴  +  56m⁵n³  +  28m⁶n²  +  8m⁷n¹  +  1m⁰n⁸

The terms will be odd if both the m-term and the n-term are odd.

These terms will be odd if both of their exponents are odd.

Therefore, there will be  8  +  56  +  56  +  8  odd terms.

The point estimate is 22/74  =  29.73%

Lower limit:  29.72%  -  3.1%  =  26.6%

Upper limit:  29.72%  +  3.1%  =  32.8%

Interval:  26.6%  <  value  <  32.8%

There are 4 ways to get a product of 64:  either of the two eights on the first spinner and either of the two eights on the second spinner.

There are 4 ways to get a product of 24: a three on the first spinner and either of the two eights on the second spinner or either of the two eights on the first spinner and a three on the second spinner.

There are 4 ways to get a product of 8: a one on the first spinner and either of the two eights on the second spinner or either of the two eights on the first spinner and a one on the second spinner.

There are 2 ways to get a product of 3: a one on the first spinner and a three on the second spinner or a three on the first spinner and a one on the econd spinner.

There is 1 way to get a product of 9: a three on the first spinner and a three on the second spinner.

There is 1 way to get a prodeuct of 1: a one on the first spinner and a one on the second spinner.

Therefore, the answer is b.

Yes. 

Answer: Yes.

The answer is [200, 325).

What do you mean, there is an answer.

It's a picture lol 

The distance is 2/3*sqrt(5).

I finally solved it!  The answer is [200, 450).  Thanks for everyone's help!

-4.9t^2 + 18t - 0.4  > 6

-4.9t^2 + 18t - 6.4 > 0      use quadratic formula to find the two t values     subtract the smaller from the larger

s+c = 50

6s + 1c = 115   subtract bottom equation  from top equation

-5s = -65

 s = 13   sandwiches         then   13 + c = 50    means  37 chips

a + b = 17.

AH:HD = 2:3.

vertecx form of parabola with vertex ( 2,4)

y   =  a ( x-2)^2 + 4     sub int e point given (-1,-1) to calculate the vlaue of 'a'

-1 = a ( -1-2)² + 4

-1 = 9a + 4

-5 = 9a

a = - 5/9

so the equation becomes    y =- 5/9 (x-2)^2 + 4     expand to get into the reqested form

                                            y = - 5/9 x^2 +20/9 x + 16/9

15 seconds is 90^o on the clock face

   this is  1/4 of the total circumference

circumference = 2 r pi

    2 r pi * 1/4 = 2 cm

         r = 2cm / (2 pi)   * 4 = 1.3 cm

2x^2 -7x+2 = 11x -15

2x^2-18x+17 = 0      Quadratic formula shows   roots = 7.92783  and 1.07217

plugging into   1/(a - 1) + 1/(b - 1)

  = ~ 14
