The correct answer is,

he value of expression 7x (3x+x) when x is 8 = 1792

Step-by-step explanation:

It is given expression is,

7x (3x+x)

Simplify 7x (3x+x)

7x (3x+x) = 7x (4x)

= 28x²

To find the value of 7x (3x+x) when x = 8

7x (3x+x) = 28x²

x = 8

28x² = 28 * 8² = 28*64 = 1792

Therefore the value of 7x (3x+x) when x is 8 = 1792
