Let A be the area of a triangle with sides of length 25,35 and 30.Let B be the area of a triangle with sides of length 25,25, and 40.Find A/B Draw diagrams to represent the two triangles and label them with their dimensions. Use the formula for the area of a triangle to find A and B.

here is where you van find ur answer

Step-by-step explanation:

look it up and click  the second one

(f • g)(3) = 186

Step-by-step explanation:

The area of a rectangle is (length)(width).

Here, (length) = x + 3 and (width) = 12x - 5, and so the area as a function of x is

(f • g)(x) = (x + 3)(12x - 5) = 12x^2 - 5x + 36x - 15.

This simplifies to:

(f • g)(x) = (x + 3)(12x - 5) = 12x^2 + 31x - 15.

Evaluating this function at x = 3, as instructed, we get:

 (f • g)(3) = (12)( - 5) = 12(3)^2 + 31(3) - 15.

Carrying out the indicated operations, we get:  108 + 93 - 15, or

(f • g)(3) = 186
