Answer:

Zamir 75%

Caleb 72%

Rosa 76%

Work

<u>Zamir</u>

.75=75%

75*40=3000

3000/ 100= 30

<u>Zamir got 30 out of 40</u> questions right

<u>Caleb</u>

30-12=18

<u>Caleb got 18 out of 25</u> questions right now find percent

18*100=1800

1800/ 25= 72

Caleb got 72%

<u>Rosa</u>

18+1=19

<u>Rosa got 19 out of 25 </u>questions correct now find percent

19*100=1900

1900/ 25=76

Rosa got 76%

(x-1)(x-3)(x+5)(x+7)=297
mihalych1998 [28]

First simplify the expression into polynomial form,

(x-1)(x-3)(x+5)(x+7)=297

x^4+8x^3-10x^2-104x+105=297

x^4+8x^3-10x^2-104x-192=0

Now factor into,

(x-4)(x+8)(x^2+4x+6)=0

Which means the solutions are,

x-4=0\implies\boxed{x_1=4}

x+8=0\implies\boxed{x_2=-8}

and then two complex solutions because determinant of the third factor D\lt0,

x^2+4x+6=0

x^2+4x+4=-2

(x+2)^2=-2\implies\boxed{x_3=i\sqrt{2}-2},\boxed{x_4=-i\sqrt{2}-2}

Hope this helps :)
