Step-by-step explanation:
By Descrates' Rule of Signs,
x² + 99x + 127 changes sign 0 times.
Hence it has 0 positive roots.
Since the discriminant b² - 4ac is also positive, there are 2 real distinct roots.
Hence both the roots are negative. (B)
Answer:
Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.
Step-by-step explanation:
It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.
We have to find the expression which represents the perimeter, in centimeters, of the triangle.
Perimeter of a triangle = Sum of its all the sides.

On combining like terms, we get



Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.
