Answer:
I will list main feature for each property and you can choose. You can comment if you want to check or have questions
Step-by-step explanation:
Isosceles - two sides are equal
Equilateral - all sides are equal
Obtuse - one angle is greater than 90 degrees
Right - one angle is equal to 90 degrees
Scalene - none of the sides is equal
Acute - all angles are less than 90 degrees
Go down the list and see if it's true or false about the given triangle
The correct answer is not up there. its -125a^7
I believe you need to solve this using the quadratic formula!
To begin, this is what it is:
x= -b ± <span>√ b^2 - 4ac / 2a
Just plug in what you have in your problem...
2 being a, 13 being b, and -24 being c.
So we get:
x= -13 </span>± <span>√13^2 - 4(2)(-24) / 2(2)
x= -13 </span><span>± √169 - 8 (-24) / 4</span>
<span>x= -13 <span>± √169 + 192 / 4</span>
x= -13 </span>± √<span>361 / 4
The square root of 361 is 19.
So you have: -13 </span><span>± 19 / 4.
Here's where you take the equation </span>-13 <span>± 19 and put the addition and subtraction sign to use.
-13 - 19 = -32
and
-13 + 19 = 6
Now all is left to do is divide the two numbers by 4.
-32/4 = -8
and
6/4 = 3/2
x = -8, 3/2</span>
well I can’t see the statements but I would say it is a right triangle
