What is square root of 5x^4-6x^5+x^6+16x^3-8x^2-8x+4 ? <br>help me pleasee !​
Natali5045456 [20]

Answer:

y = (x + 1)(x - 0.586) ( x - 3.414)

Step-by-step explanation:

I sure wouldn't recommend doing this by trial and error.

I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.

y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2

are the listed roots.

The square root is

y = (x + 1)(x - 0.586) ( x - 3.414)

Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2

you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Two rectangle are similar, the first 4 in wide and 15 in long. The second is 19 in. Wide. Find the length of the second rectangl
AleksandrR [38]

Answer:

the length of the second rectangle is 33.75 in

Step-by-step explanation:

The computation of the length of the second rectangle is as follows

Let us assume the length of the second triangle be x

Now

The equation would be

4 ÷ 15 = 9 ÷ x

Now do the cross multiplication

4x = 15 × 9

4x = 135

x = 33.75 in

Hence, the length of the second rectangle is 33.75 in

I really need help please
morpeh [17]

Step-by-step explanation:

GI = GI (common)

GJ=HI(given)

GH = JI(given)

so triangle GJL and triangle GHI are congruent by S.S.S axiom,

<J=<H (corresponding angle of congruent triangles are equal)

Triangle and triangle are similar. What is the measure of side ?
snow_lady [41]

When two triangles are similar, they're sides are in proportion.

In order to find the unknown side, we first have to find the ratio of the larger triangle to the smaller triangle.

We can use the sides TV and LN to make the proportion.

\frac{LN}{TV} = \frac{21}{6}

The ratio between the two triangles is 21:6

Now we can solve for the unknown side.

\frac{21}{6} = \frac{LM}{8}

Cross multiply:

8 * 21 = 6 * LM

168 = 6LM

Divide both sides by 6:

LM = 28

The unknown side's length is 28 centimeters

Good luck!
