LMN = QPR What is the value of x in degrees?

Mathematics
1 answer:
Paul [167]4 years ago
4 0

Answer:

x = 72 degrees

Step-by-step explanation:

If triangle LMN = triangle QPR, that means:

- angle L (x) equals angle Q

- angle M equals angle P

- angle N equals angle R

We know angle Q equals 72 degrees and we know angle Q equals angle L. Since angle L is the "x" we are looking for, we know that x = 72 degrees.

Need help using synthetic division! ​
viktelen [127]

Answer:

3x^{2} -3x+8-\frac{9}{x+1}

Step-by-step explanation:

Since we're dividing the polynomial by (x+1), we'll be using -1 to start the division.

Before setting the division up, let's list the coefficients of x from descending powers and the constant.

The coefficient of x^{3} is 3

Since we don't see an x^{2}, the coefficient will be 0.

The coefficient of x is 5.

Lastly, the constant, which is the term without the x is -1.

Refer to the attached picture before continuing.

After referring to the picture, we now have the coefficients for the quotient.

The coefficient of x^{2} is 3.

The coefficient of x is -3.

The constant is 8.

Lastly, since the last number is not zero, it's the remainder just like regular division. This can be tricky to remember, but -9 is not the actual remainder.

The remainder is actually \frac{-9}{x+1}.

Now putting all the pieces together, we get:

3x^{2} -3x+8-\frac{9}{x+1}

Which expression is equivalent to 5y^3/(5y)^-2​
Serggg [28]

Answer:

5^3  y^5

125 y^5

Step-by-step explanation:

5y^3/(5y)^-2​

Distribute the exponent in the denominator

5y^3/(5 ^-2 y^-2)

A negative exponent in the denominator brings it to the numerator

5y^3 5 ^2 y^2​​

Combine like terms

5 * 5^2  * y^3 5^2

We know that a^b * a^c = a^(b+c)

5^(1+2) * y^( 3+2)

5^3  y^5

125 y^5

Which of the following represents x = y written in general form? 2 x - y = 0 1/2 x - y = 0 x - 1/2 y = 0
Marta_Voda [28]

Answer:

x - y = 0

Step-by-step explanation:

General form of equation of straight line is

ax + by = c

that is we have to keep terms containing x and y on LHS and term independent of x and y on RHS.

given

x = y

there, no term independent of x and y

now we have to bring y one RHS

for that we subtract y from LHS and RHS

x - y = y -y

=> x - y = 0

Thus, option x - y = 0 is the correct answer.
