Answer:
x=5
Step-by-step explanation:
First you need to combine the like terms. Add the two x-terms together and you get 8x, then subtract 8 from both sides of the equation. You now have 8x=40. Just divide each side by 8 and you end up with x=5.
Answer:
- 8x = - 32
Step-by-step explanation:
Given
1 + 2x + 1 = 10, that is
2 + 2x = 10 ( subtract 2 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Then
- 8x = - 8 × 4 = - 32

Answer:
there may be 16 but I am not sure
Answer:
<em>h = 3</em>
Step-by-step explanation:
What we have here is a classic case of pythagorean theorem. 5 is the hypotenuse and 8 is divided directly in half to make one of the legs equal to 4. inputting this into the pythagorean equation we get 4^2 + h^2 = 5^2 or 16 + h^2 = 25. 25 - 16 = 9 and the square root of 9 is 3. therefor <em>h = 3</em>
