I can't read the number 5 but here is number 6.

X+8 = 15. x = 7, this goes in the less than 10 box.
9x= 99 x = 11, this goes int he greater than 10 box.
x + 2 = 11 x = 9 this goes in the less than 10 bx.
6x= 54 x = 9 this goes in the less than 10 box.
x + 4= 13 x = 9 this goes in the less than 10 box.
5x = 60 x = 12 thsi goes i the greater than 10 box.

Hope this helps!

4.
2x=10
x=5
Solution x=5
5.
Let x represent free throw that Juan have to make which is:
6+x=15
Subtract 6 for both side
x=9. As a result, Juan had to make 9 more free throw.

6.
x+8=15
x=7

9x=99
x=11

x+2=11
x=9

6x=54
x=9

x+4=13
x=9

5x=60
x=12.
As a result,
Greater than 10:
9x=99, and 5x=60

Less than 10:
x+8=15, x+2=11, 6x=54, and x+4=13. Hope it help!

Answer:

$\large\boxed{B.\ x=\pm1\ and\ x=\pm2\sqrt2}$

Step-by-step explanation:

$x^4-9x^2+8=0\\\\x^{2\cdot2}-9x^2+8=0\qquad\text{use}\ (a^n)^m=a^{nm}\\\\(x^2)^2-9x^2+8=0\\\\\text{substitute}\ x^2=t\geq0\\\\t^2-9t+8=0\\\\t^2-t-8t+8=0\\\\t(t-1)-8(t-1)=0\\\\(t-1)(t-8)+0\iff t-1=0\ \vee\ t-8=0\\\\t-1=0\qquad\text{add 1 to both sides}\\t=1\geq0\\\\t-8=0\qquad\text{add 8 to both sides}\\t=8\geq0$

$t=x^2\to x^2=1\ \vee\ x^2=8\\\\x^2=1\Rightarrow x=\pm\sqrt1\to x=\pm1\\\\x^2=8\Rightarrow x=\pm\sqrt8\to x=\pm\sqrt{4\cdot2}\to x=\pm\sqrt4\cdot\sqrt2\to x=\pm2\sqrt2$
