SOVA2 [1]

Answer:

Step-by-step explanation:

Factors of 35 = 1,5,7 and 35

Factors of 15 = 1,3,5 and 15

=> Largest prime number that is a factor of 35 = 7 (7 is a prime number)

=> Smallest prime number that is a factor of 15 = 3 ( 1 is neither a prime no. nor a composite one)

The length of a rectangle is 7cm more than twice the width. When just the width is tripled, the perimeter of the resulting recta

grin007 [14]

Answer:

Length = 27cm

Width = 10cm

Step-by-step explanation:

Let the length of the rectangle be x

Let the width be y

If the length of a rectangle is 7cm more than twice the width, then;

x = 2y + 7

Since P = 2(x+y)

P = 2(2y+7+y)

P = 2(3y+7)

P = 6y+14

If the width is tripled, P = 74

74 = 6y+14

6y = 74-14

6y = 60

y = 10

Since x = 2y+ 7

x = 2(10) + 7

x= 20+7

x = 27

Hence the original dimension is 27cm by 10cm
