Since the triangle DEF is an equilateral triangle and x is the height of this triangle, we can use the following formula for the height of an equilateral triangle:
![h=\frac{l\sqrt[]{3}}{2}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7Bl%5Csqrt%5B%5D%7B3%7D%7D%7B2%7D)
Where 'l' is the length of the triangle side.
So, using l = 13, we have:
![\begin{gathered} x=\frac{13\cdot\sqrt[]{3}}{2} \\ x=\frac{13\cdot1.73}{2} \\ x=11.2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D%5Cfrac%7B13%5Ccdot%5Csqrt%5B%5D%7B3%7D%7D%7B2%7D%20%5C%5C%20x%3D%5Cfrac%7B13%5Ccdot1.73%7D%7B2%7D%20%5C%5C%20x%3D11.2%20%5Cend%7Bgathered%7D)
So the value of x is 11.2
Step-by-step explanation:
First we will multiply 4 by 12 = 48
Then we will find the factors of 48 that when we add or subtract it the answer is 2 so
12x 2 - 6x + 8x - 4
6x ( 2x - 1) + 4 (2x - 1)
So ( 2x - 1) and (6x + 4) are the factors
Option C is the correct answer
Answer:
3.13
Step-by-step explanation:
There were 5.23 apples and 2.1 of them were eaten by bob. How many are left?
Hello, your answer is: <span>1079, because remember, this equation represents
*800 - (-279)
so, you need to use the method of KCC, or, k=keep, c=change, c=change.
you keep the 800 positive, switch the (-) subtraction sign to a (+) addition sign, and also, make the (-279) a positive 279. so you turn out with:
*800 + 279, which equals = 1079
*youre welcome!!!! can you please pick this answer as the brainliest??? please i really need it, thank you!!! :)
