Answer:
10b +13 +18a
Step-by-step explanation:
The perimeter of a triangle= Sum of the length of all sides
Therefore,
Perimeter = (10a +9) + (8a - 3) + (10b + 7)
= 10a +8a +10b + 9+7-3
= 18a + 10b + 13
<span>The answer is C. a circle with a diameter of 12 units. The circumference of the circle with the radius r is: C = 2 r π. We know that circumference is 24π units. So: C = 2rπ and C = 24π units. Therefore: 2rπ = 24π. Divide both sides by π: 2rπ / π = 24π / π. Thus: 2r = 24. r = 24/2. r = 12 units.</span>
