What is 2 over 7 is greater than 4 over 12

WINSTONCH [101]

The value 2 / 7 is greater than 4 / 12 is - 1 / 21

<h3>How to perform subtraction in algebra?</h3>

To know the value 2/7 is greater by 4 / 12, we have to subtract 4 / 12 from 2 / 7 .

Therefore,

2 / 7 - 4 / 12 = 24 - 28/84

Expand the function. f(x)=(x + 7)^3

Marta_Voda [28]

Answer:

$f(x) = {x}^{3} + 21 {x}^{2} + 147x + 343$

Step-by-step explanation:

$(x + 7 {)}^{3}$

${x}^{3} + 3 {x}^{2} \times 7 + 3x \times {7}^{2} + {7}^{3}$

${x}^{3} + {x}^{2} \times 7 + 3x \times 49 + 343$

${x}^{3} + 21 {x}^{2} + 147x + 343$

Therefore:

$f(x) = {x}^{3} + 21 {x}^{2} + 147x + 343$
