Olin [163]

Answer:

f(-2) =8

Step-by-step explanation:

f(x) = 3x^2+x-2

Let x = -2

Write the scale factors and values for x for the pairs of similar triangles below. 9 cm x cm 4 cm 2 cm Scale Scale Factor: X=

Neporo4naja [7]

The scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.

<h3>Scale Factor of Similar Triangles</h3>

Scale factor of similar triangles is the ratio of their corresponding sides.

Given the two similar triangles in the diagram attached below, we have the following scale factor as:

Scale factor = 2/4 = 1/2

Therefore:

x = 1/2 × 9

x = 4.5 cm.

Therefore, the scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.
