Charlie solved an equation. as shown below:

1 answer:

7 0

Charlie's solution is incorrect. He did step 2 incorrectly. Because the equation is 5x = 30, he needs to divide by 5 instead of subtract 5 from both sides.

If this was done correctly, it would like like this:

Step 1: 5x = 30
Step 2: x = 30/5
Step 3: x = 6

This equation will only have one solution, x = 6.

Find the leg of each isosceles right triangle when the hypotenuse is 5 square root 6

kozerog [31]

Hypotenuse = 5√6

Let the length of each leg be x, since it is Isosceles .

x² + x² = (5√6)²

2x² = (5 * 5 * √6 * √6)

2x² = 150

x² = 150/2

x² = 75

x = √75

x = √(25 * 3)

x = √25 * √3

x = 5√3
