What number Samuel must multiply each side length of his original photo 3 by 5 to enlarge 4 1/2 by 7 1/2

3/2

Step-by-step explanation:

To get the number we divide the corresponding sides; dividing the enlarged size by the original size

4 1/2 / 3 = 4 1/2 × 1/3 = 9/2. × 1/3 = 3/2

The factor is 3/2 = 1 1/2.

When you multiply 5 by 3/2 we get 15/2 = 7 1/2

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
