I would approach this question by changing the equations from polar to cartesian form. Do you know how to do that?
The price of the 9 cans of beans is 54$
Perimeter of the triangle ABC is 18.7 units.
Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).
Length of the side AB =
AB =
AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side BC =
BC =
BC =
BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side CA =
CA =
CA =
CA = 4.47 units = 4.5 ( rounded to the nearest 10th)
Perimeter of the triangle ABC = sum of all three sides = (7.1 + 7.1 + 4.5) units = 18.7 units
Step-by-step explanation:
(3 × 10) × 8 = 3 × (10 × 8)
It's an Associative Property of addition:
<em>(a + b) + c = a + (b + c)</em>
<em></em>
Check it:
Left side: (3 × 10) × 8 = 30 × 8 = 240
Right side: 3 × (10 × 8) = 3 × 80 = 240
CORRECT
