Here, angle (3x-1) is supplementary with 5x, so their sum would be equal to 180

3x - 1 + 5x = 180
8x = 180 + 1
x = 181/8
x = 22.625

Hope this helps!

Find all real solutions and show work: <br> 2x^3-3x^2+18x-27=0
Amiraneli [1.4K]

Given:

The given equation is

2x^3-3x^2+18x-27=0

To find:

All the real solutions.

Solution:

We have,

2x^3-3x^2+18x-27=0

It can be written as

x^2(2x-3)+9(2x-3)=0

(2x-3)(x^2+9)=0

Using zero product property, we get

(2x-3)=0 and (x^2+9)=0

2x=3 and x^2=-9

x=\dfrac{3}{2} and x=\pm\sqrt{-9}

We know that x=\pm\sqrt{-9} is an imaginary number because there is a negative sign under the square root.

Therefore, x=\dfrac{3}{2} is the only real solution of the given equation.

I’m the parallelogram above, what is the value of x+y <br><br> Help please
olga2289 [7]

Answer:

248°

Step-by-step explanation:

y = 180°- 56°

  = 124°

x = 124° because opposite angles of a parallelogram are equal

x + y = 124° + 124°

        = 248°
