Answer: Second option.
Step-by-step explanation:
1. To solve this problem you can applly the quadratic formula, which is shown below:
2. The quadratic equation is:
3. Then:
a=1
b=-10
c=-10
4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:
x=5±√35
Answer:
The are a is 6
The length of h = 2.4
Step-by-step explanation:
This is a 3 4 5 special triangle so the length of the hypotenuse is 5
The area for a triangle is calculated by multiplying height to the base and that divided by two
Since it's a right triangle we can take any side length as the height and the result wouldn't change
4×3÷2 = 6 is the area for this triangle now we can use thus information to find the length of h :
h × 5 ÷ 2 = 6
5h = 12
h = 2.4
I just guessed and it is 108
