You need to isolate x.
71 - 5x = 9x - 13
Add 13 to both sides.
84 - 5x = 9x
Add 5x to both sides.
84 = 14x
Divide both sides by 14.
6 = x
<h3>The answer is x = 6.</h3>
The answer is: 12 centimeters.
The explanation is shown below:
1. By definition, all four sides of the square are equal and the diagonals are equal too.
2. Keeping the information above on mind, you know that AC and BD are equal:
3. Then, the length of BD is twice BE. So, you can calculate it as following:
4. Therefore, the lenght of AC is:
First one is
(2x+5)
Second one is
“All of these are correct”
Hope this helped
To solve this I'm going to split the middle term.
First multiply the first and last terms:
24x^2
So find two numbers that multiply to 24x^2 and add to 11x.
This would be 3x and 8x
Rewrite the problem as
4x^2+3x+8x+6
Take the first and 3rd and 2nd and 4th terms
4x^2 and 8x
and
3x and 6
Factor by grouping
Take out a 4x for the first group to get 4x(x+2)
Take out a 3 for the 2nd group to get 3(x+2)
Rewrite as (4x+3)(x+2)
Hope this helps.
The slope would go vertically starting it at 5. you place your dot at 5 and draw a line going up and down throughout both the top and bottom of the right side of the graph. hope it helped
