Factor completely 2x5 + 10x4 − 22x3.
Luba_88 [7]

Given equation is :

2x^{5}+10x^{4}-22x^{3}=0

Taking out 2x^{3} common we get,

x^{2}+5x-11=0

Now solving this we get,

As 11 is not factor-able, we will solve it using the formula,

x=\frac{-b+\sqrt{b^{2}-4ac}}{2a}

a=1 b=5 and c=-11

we get,

x=\frac{-5+\sqrt{69} }{2} and x=\frac{-5-\sqrt{69} }{2}

ryzh [129]
Let w and 2w-5 be the width and length. Then:
w(2w-5)=33
2w²-5w-33=0
(2w-11 )(w+3 )=0
w=11/2 or -3
If the width is 11/2 yd, then the length is 6 yds

Please help solve 20 points.
Bond [772]

Answer: scroll down to find out :)

Step-by-step explanation:

This isn't a hard equation, so I would just use the points and figure something out.

Some obvious points are (3, 6), (6, 12), and (7, 14). Immediately, we notice that the y coordinate is 2 times the x coordinate.

So, the equation would be y = 2x.

<em>P.S. Let me know if I got it wrong! I'll be more than happy to fix it :)</em>
