Answer:

One solution was found :

                  x = 0

Step-by-step explanation:

10(x-2)=-20

One solution was found :

                  x = 0

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    10*(x-2)-(-20)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 10 • (x - 2) -  -20  = 0

Step  2  :

Equation at the end of step  2  :

 10x  = 0

Step  3  :

Solving a Single Variable Equation :

      Solve  :    10x = 0

Divide both sides of the equation by 10:

                    x = 0

One solution was found :

                  x = 0

A drawing of a triangle. The base equals 15 centimeters and height equals 8 centimeters.
Effectus [21]

Answer:

17

Step-by-step explanation:

If we are finding the long angled side (the hypotenuse), we must keep in mind the Pythagorean theorem. This states that in order to find the answer, we must follow: A squared + B squared = C squared. A and B are known as the legs and we use these for A and B. After squaring both 15 and 8 we get 225 + 64= 289. Now that we have our answer of 289, we can square this to find our hypotenuse which is 17. To find the square root, you multiply different numbers by themselves until you reach your answer. 17 x 17 = 289 so the hypotenuse is 17 centimeters long. I hope this helps! :)

Solve the following inequality.<br> 2x + 2(x+5) &lt;+4(8 – 20)
Ilia_Sergeevich [38]

Answer:

x <-14.5

Step-by-step explanation:

2x + 2(x+5) <+4(8 – 20)

Distribute

2x+2x+10 < 4 (-12)

4x +10 < -48

Subtract 10 from each side

4x+10-10 <-48-10

4x< -58

Divide each side by 4

4x/4 < -58/4

x <-14.5
