Pls help like asap Directions: Simplify by combining like terms in each of the following expressions.

1. 10s2 + 10s2 - 13st =

2. 13st + - 2st - t2 =

3. x2+ x2 + x3=

4. 6 x - 6 x + 2=

5. 24x - 3s - 4t=

6. 86 + 86x - 1 =

7. 4x + 3x - 2 =

8. 7s - 4s + 3s =

9. 12 +11x - 10 x =

10. 12x + 24 x - 3 x - 4 =

11. 16t + 8t - 12t =

12. 17g + 19g - 2g +g =

13. 16 + 16 -16 + 16x =

14. 4s - 3s + 3s =

15. 12t - 11t + t =

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

the answer is b 9. hope you got it down bud.

for nitrogen to be a liquid, its temperature must be within 12.78 °f of –333.22 °f. which equation can be used to find the maximum and minimum temperatures at which nitrogen is a liquid, x?

the equation that can be used to find the maximum and minimum temperatures is

|x +   ⇒ 333.22| =   ⇒ 12.78.
