Answer:
40
Step-by-step explanation:
3, 6, 9...
120 = 3+(n-1)3
120 = 3+3n-3
120 = 3n
120 / 3 = 3n / 3
40 = n
Note that the area of a square is: A = s² (s being side). Also note that all the sides of the square are congruent and have the same measurement.
Plug in 37 for A
37 = s²
Isolate the s. Note the equal sign. What you do to one side, you do to the other. Root both sides
√37 = √s²
s = √37
Change the root to a decimal
s = √37 = ~6.1 (rounded to the nearest tenth)
6.1 in is your answer
hope this helps
Here is your first answer:
First find whats common which is 6:
-4×2=-8
3×2=6
-3×3=-9
2×3=6
Subtract -9 and -8
But use KCC which makes the equation...
-9+8=-1
-1/6
Here is your second answer:
First use KCC to Chang the equation into...
-3.9
-8.9
Then add:
9+9=18
=-1.28
Here is your third answer:
First change the equation (KCC):
2.9
9.4
9+4=13
3.9=12
=1.23
There are your answers:
