Answer:

(2x + 1)(x - 3)

2 {x}^{2}  - 5x - 3 = 0

(2x + 1)(x - 3)  = 0

I'm not too sure on this can i have some help
Ganezh [65]
Welcome to Brainly. We are here to help! 

Similar polygons vary directly with each other. They have the same scale.

Something I notice about the polygons is that both of the sides are decreased by 10.

40-30= 10 and 28-18=10

Try to find the scale.

40/28= 1.42857....

30/18= 1.666666777


I would say these are not similar polygons. They do not share the same scale.

I hope this helps!

The answer choices are in the photo
kirill [66]

Answer:

35 units²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 5, thus

A = \frac{1}{2} × 14 × 5 = 7 × 5 = 35 units²
