The scale drawing of a field in the shape of a triangle is shown below

70 m^2.

Step-by-step explanation:

Area of the triangle = 1/2 * base * height.

Counting the squares on the  coordinate plane:

Base = 7, height  = 5

Each square = 2 meters

So the area = 1/2 * 14 * 10

= 70m

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
