Triangle abc is a right triangle
the length of bc is 5 units.
the area of abc is square units.

50 square units.

Step-by-step explanation:

Given in the picture is a right angled triangle

The coordinates of A are (-9,10) and B are (7,-2) and C is (4,-6)

Given that BC = 5 units

AB = distance between A and B

=distance between two points (-9,10) and (7,-2)

=

Thus if we consider BC as base then AB is the height

Area of triangle = 1/2 bh = 1/2 (5)(20)

= 50 square units

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:
