What is the value of the expression when x = 4?
8x^2 + 3x

The value of the expression at x = 4 is 140

Step-by-step explanation:

Let us solve the question

∵ The expression is 8x² + 3x

∵ x = 4

→ To find the value of the expression at x = 4 substitute x by 4 in

    the expression, then calculate the value of it

∵ The value of the expression = 8(4)² + 3(4)

→ Solve the power first

∴ The value of the expression = 8(16) + 3(4)

→ Simplify each term using multiplication

∴ The value of the expression = 128 + 12

→ Add the terms

∴ The value of the expression = 140

∴ The value of the expression at x = 4 is 140

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
