What factor must you multiply a number in order to double its square root?

Let x = the number

Let c = the factor

You want

√(cx) = 2√x

Solve for c:

cx = 4x

c = 4

You need to multiply by 4 to double the square root. Have a great day!!

i just took the test, the correct answer is .. 31.5 in.

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
