Answer:
Perimeter of larger triangle is 40.
Step-by-step explanation:
Given:
Perimeter of smaller circle = 16
Ratio of corresponding side = 2:5
We need to find the perimeter of the larger triangle.
Solution:
Let the perimeter of the larger triangle be 'x'.
Therefore by theorem which states that;
" When a triangle have scale factor a:b then the ratio of the perimeters is a:b".
Here Ratio is 2:5, so we can say by theorem, Ratio of perimeters is 2:5
framing in equation form we get;
Substituting the values we get;
By Cross multiplication we get;
Dividing both side by 2 we get;
Hence Perimeter of larger triangle is 40.

<h3>Answer:</h3>
±12 (two answers)
<h3>Explanation:</h3>
Suppose one root is <em>a</em>. Then the other root will be -3<em>a</em>. The product of the two roots is the ratio of the constant coefficient to the leading coefficient:
(<em>a</em>)(-3<em>a</em>) = -27/4
<em>a</em>² = -27/(4·(-3)) = 9/4
<em>a</em> = ±√(9/4) = ±3/2
Then the other root is
-3<em>a</em> = -3(±3/2) = ±9/2 . . . . . . the roots will have opposite signs
We know the opposite of the sum of these roots will be the ratio of the linear term coefficient to the leading coefficient: b/4, so ...
-(a + (-3a)) = b/4
2a = b/4
b = 8a = 8·(±3/2)
b = ±12
_____
<em>Check</em>
For b = 12, the equation factors as ...
4x² +12x -27 = (2x -3)(2x +9) = 0
It has roots -9/2 and +3/2, the ratio of which is -3.
For b = -12, the equation factors as ...
4x² -12x -27 = (2x +3)(2x -9) = 0
It has roots 9/2 and -3/2, the ratio of which is -3.
No, only the value of what you are finding the absolute value of can be a negative. Examples: |-2|=2 |2|=2
