Answer:

There is no specific method you can solve it as you like

Step-by-step explanation:

you can do it as a normal equation first get rid of the (x-9) by multiplying the whole radical by x-9/x-9, then you will get rid of the x-9 down and you will have (x-9) . (x+6) . (x-1) \leq 0 then multiply them together and solve it normally. Also dont forget to do the check part :)

If you need further help comment down :)

Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

\large{ \frac{ {x}^{2} }{ {5}^{2} }  =  {4}^{2} }

First, we simplify 5² and 4²

\large{ \frac{ {x}^{2} }{25}  = 16}

Multiply the whole equation by 25 to get rid of the denominator.

\large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\  \large{ {x}^{2}  = 400}

Square both sides and solve the equation.

\large{ \sqrt{ {x}^{2} }  =  \pm{ \sqrt{400} }}

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

\large{x = \pm{20}}

Which property of polynomial addition says that the sum of two polynomials
ArbitrLikvidat [17]

Answer:

The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.

Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.

In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.

CONGRUENT TRIANGLES WORKSHEET. NEED ASAP DUE TODAY
WINSTONCH [101]

Answer:

Congurent triangles are those which map onto them selves perfectly. This means they share the same angle measurements and side lengths. Therefor we can figure out the side lengths by using the information in both triangles.

AD=5x+11

in the congurent triangle, the corresponding side equals:

CM=7x-3

CM and AD are congurent triangles meaning their sidelengths equal the same. Therefore...

5x+11=7x-3

Now we just solve to find the length of AD and CM (equal lengths)

5x+11=7x-3

11=2x-3

14=2x

7=x

x=7

If x=7 then we can plug it in for AD to find the side length.

5(7)+11=46

Notice that CM equals the same 7(7)-3=46

This is because... they are congruent triangles.

These rules also apply for all angle measurements of congruent triangles:

The m<v is equal to the meaasure of E (corresponding angles in congrurent triangles are equal)

We already astablished what x was (x=7) meaning if we find the measure of E then we have the measure of V sicne they are corresponding angles in a congrurent triangle.

(6x7+1)=43°

therefore the m<v is equal to 43°

46 and 43° is your answer
