which expression shows 7 + 21 written as a product of two factor
7 + 21 = 28
28 = 4 x 7
Therefore, 7 + 21 written as a product of two factors is 4 x 7.
which expression shows 7 + 21 written as a product of two factor 3(3+7) 3(1+7) 7(3+3) 7(1+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).
which expression shows 50 + 30 written as a product of two factor
10(5+2) 10(5+3) 5(10+3) 5(10+7)
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).
To write 7 + 21 as a product of two factors, we need to find two numbers that can be multiplied together to give us 7 + 21.
Let's factor out the common factor of 7 from both numbers:
7 + 21 = 7(1 + 3)
So, 7 + 21 can be written as the product of 7 and (1 + 3).
To write the expression 7 + 21 as a product of two factors, you need to find two numbers whose product equals 7 + 21.
Let's break it down step by step:
1. Start with the expression 7 + 21.
2. Look for two numbers whose product equals 7 + 21.
3. First, we can observe that 7 + 21 is equal to 28.
4. Now, find two numbers whose product equals 28. These numbers can be any two numbers that multiply together to give 28.
5. One possible pair of numbers that satisfy this condition is 4 and 7, because 4 × 7 = 28.
6. Therefore, the expression 7 + 21 can be written as a product of two factors: 4 × 7.
