Answer:
<h2>64x³ - 432x² + 972x - 729</h2>
Step-by-step explanation:
Write the statement into an expression
<h2>(4x - 9)³</h2><h2 /><h3>Now multiply that out...</h3><h3 /><h3>(4x - 9)²(4x - 9)</h3><h3 /><h3> Foil the first binomial</h3><h3 /><h3> (16x² - 72x + 81)(4x - 9)</h3><h3 /><h3>Multiply the two polynomials together</h3><h3 /><h3> 16x²(4x) - 72x(4x) + 81(4x) + 16x²(-9) - 72x(-9) + 81(-9)</h3><h3 /><h3> 64x³ - 288x² + 324x - 144x² + 648x - 729</h3><h3 /><h3>combine like terms...</h3><h3 /><h3>64x³ - 432x² + 972x - 729</h3>
The smallest natural number is 1 and the smallest whole number is 0 so
1x0=0
i hope that’s right
Answer:
$167.20
Step-by-step explanation:

0.09 x 153.4 = 13.8
the total cost of the meal is $167.20
