Solve for x
( I already did 1 and 3 )

Answer for problem two: 2

Answer for problem four: 1/3 (one-third)

Answer for code: FHDA

Step-by-step explanation:

For Two: I had to multiply 4 to both sides which would cross the 4 on the left side out and the right side would become 20. Then, I just subtracted 18 to leave x alone and got x=2.

For Four: I had to subtract one from both sides to make 33x on the left and 11x on the right. 33x=11. Then, I had to do: 11/33 to leave the x alone and I ended up with 1/3.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
