1) simplify 5m - 13n - n + 4m.

2) 15 - (-11) =

3) simplify 3(x - 4) + 8(x + 2).

4) add -54 + 18.

5) evaluate x^2/y + x^2/z , if x = 10, y = -5, and z = -2.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
