33 marbles

2/5 is .4

Multiply .4 by 40 to get 16

Subtract 16 from 40 to get 24

Add 9 to 24 to get 33

The area of a triangle is the amount of space on the triangle

The expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

The coordinates of the triangle are given as:

$R = (-5,6)$

$S = (3,4)$

$T = (-2,2)$

The area (A) of a triangle from its coordinates or vertices are:

$A = \frac 12|x_1(y_3 -y_2) +x_2(y_3 -y_1) + x_3(y_2 -y_1)|$

Substitute values for x's and y's

$A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

Hence, the expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

Answer: 0

Step-by-step explanation: The answer would be 0 since if y = -4, the graph of the line would just be a horizontal line through the point (0,-4). This would be like saying that y = 0x-4. Hope this helped!
