which expression shows 7 + 21 written as a product of two factor

Answer 1

7 + 21 = 28

28 = 4 x 7

Therefore, 7 + 21 written as a product of two factors is 4 x 7.

Answer 2

which expression shows 7 + 21 written as a product of two factor 3(3+7) 3(1+7) 7(3+3) 7(1+3)

Answer 3

7 + 21 = 28

28 = 4 x 7

Therefore, 7 + 21 can be written as a product of two factors in several ways, including:

- 3(3 + 7) = 3 x 10 = 30
- 3(1 + 7) = 3 x 8 = 24
- 7(3 + 3) = 7 x 6 = 42
- 7(1 + 3) = 7 x 4 = 28

So, the expressions that show 7 + 21 written as a product of two factors are 3(3+7), 3(1+7), 7(3+3), and 7(1+3).

Answer 4

which expression shows 50 + 30 written as a product of two factor
10(5+2) 10(5+3) 5(10+3) 5(10+7)

Answer 5

50 + 30 = 80

80 = 8 x 10

Therefore, 50 + 30 can be written as a product of two factors in several ways, including:

- 10(5 + 2) = 10 x 7 = 70
- 10(5 + 3) = 10 x 8 = 80
- 5(10 + 3) = 5 x 13 = 65
- 5(10 + 7) = 5 x 17 = 85

So, the expression that shows 50 + 30 written as a product of two factors is 10(5+3).
