scale factor is the ratio of two similar geometric figures of their
corresponding sides. The scale factor is calculated by locating the
corresponding sides on each figure. We do as follows:
256/x = 4/9
x = 576 m^2
side length = 24 m

Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.

The two points are C(2,-1) and D(5,3). Using the distance formula, we get



On further simplification, we get



The distance from point C to D is 5 units. Therefore, the correct option is A.
Answer:
19
Step-by-step explanation:
f(x) = 3x^2-3x + 1
Let x = -2
f(-2) = 3( -2)^2-3*-2 + 1
= 3 * 4+6+1
= 12 +6+1
= 19
