2X10 would work, as would 5X4.
A number sentence is a mathematical equation, such as 2x6+5x4=32.
To find another multiplication equation that equals 20, we can consider 10 x 2 = 20. This equation represents multiplying 10 by 2, which also results in a product of 20. Multiplication is a mathematical operation that involves repeated addition, where the multiplicand (10) is added to itself a certain number of times (2) to reach the product (20).
x^5+2x^4+4x^2+2x-3
8x + 5x + 9 = 61 Collect 'like' terms. 13x + 9 = 61 Subtract '9' from both sides 13x = 52 Divide both sides by '13' x = 52/13 x = 4
