(simplify. √18) a.√36 b.√32 c.√29 d.√23

 None of those answers are the simplified form of that radical.

The simplified form would be 3 or in decimal form.

Step-by-step explanation:

I got the simplified version of sqr root 18 very easily.

First I broke it up into sqr root 9 * sqr root 2

I simplified sqr root 9 as 3 and then left sqr root 2 alone as it cannot be simplified further

That is how I got my answer of 3

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i think the answer is true
