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>
Answer:
the is k=-0.4
Step-by-step explanation:
sorry if I did it wrong
4 mph is a rate, and is represented by a straight line thru the origin with slope 4/1.
Draw a set of coordinate axes and label them t (for time) and d(for distance).
Start with your pencil point at the origin. Arbitrarily move this point 3 spaces to the right, and from there move it 4 spaces up. You'll be at (3,4).
Draw a straight line from the origin (0,0) to the point (3,4).
The answer is x(x-8)(x+8)
Here is the process;
x^3-64x
x(x^2-64)
You know that it will be a x- and a x+ becuase there is no middle x value
x(x-)(x+)
x(x-8)(x+8)
