Expand the following using either the Binomial Theorem or Pascal’s Triangle. You must show your work for credit. (x - 3)^5
Rudiy27
I used bionomial expansion up to and including the term x^{3}

(-3 + x)^{5}

-3^{5} (1 +  -\frac{1}{3}x)  ^{5}

-243 (1 +  -\frac{1}{3}x)  ^{5}

n = 5
x = - \frac{1}{3}x


Binomial expansion:

1 + nx +  \frac{n(n-1) x^{2} }{2!} + \frac{n(n-1)(n-2) x^{3} }{3!}


Therefore:

1 + (5*-  \frac{1}{3}x) +  \frac{5(4) (- \frac{1}{3}x)^{2}  }{2} + \frac{5(4)(3) (- \frac{1}{3}x)^{3}  }{6}

=

1 -  \frac{5}{3} x +  \frac{10}{9} x^{2} -  \frac{10}{27}  x^{3} 



Multiply by -243

=

-243 + 405x - 270x^{2} +  90  x^{3}

If two sides of a triangle measure 4 cm and 6 cm what could be the measure of the third side? A. 9 B. 10 C. 11 D. 12
lesya692 [45]

Answer:

A. 9

Step-by-step explanation:

Triangle Inequality:  the lengths of any two sides of a triangle add up to more than the third side.

B. 10 can't be the answer because the 4 cm and 6 cm sides would just meet at a point on the 10 cm sides.

C. 11 and D. 12 can't be answers because the 4 cm and 6 cm sides would not meet (kind of like windshield wipers that are too short).

A 40 yd polygon and 15 yd polygon are similar. find the area of their ratios
Lubov Fominskaja [6]
Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 = <span> <span> <span> 2.6666666667 </span> </span> </span> <span> <span> <span> 2.6666666667^2 = </span></span></span> <span> <span> <span> 7.1111111111
</span></span></span>
<span><span><span> </span> </span> </span> So, the 40 yard polygon has <span> <span> 7.1111111111</span>times the area of the 15 yard polygon.
