17) replace the given number for "x" and evaluate

a) x² + 2x + 1   ; when x = 3

  3² + 2(3) + 1

= 9 + 6 + 1

= 16

b) x² + 2x + 1   ; when x = -4

  (-4)² + 2(-4) + 1

= 16 - 8 + 1

= 9

c) x² + 2x + 1   ; when x = 3

  (-22.872)² + 2(-22.872) + 1

= 523.128384 - 45.744 + 1

= 478.384384

Find the total cost for a $30 bat;15% discount
noname [10]
An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.
