The height of a triangle is 1.95 centimeters less than 2.5 times the corresponding base. the area of the triangle is 112.8 square centimeters. the quadratic equation that correctly models this situation is 2.5x^2−1.95x=225.6 or 2.5x^2−1.95x−225.6=0, where x represents the base of the triangle. how long is the base of this triangle?

9.897 cm ( approx )

Step-by-step explanation:

Given equation is,

Where,

x = base of the triangle, ( in cm )

By further simplifying the above equation,

By quadratic formula,

Since, side can not be negative,

Hence, the length of the base = 9.897 cm.

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
