2(3x-8) should be the answer
It would be 8 hours because you are adding 5 and 3 to get a total
Answer:
31
Step-by-step explanation:
CPCTC and Parallel concurrency theorem
Use the distance formula to find the value of the side lengths.
d=√((x1-x2)²+(y1-y2)²
d of side AC is 6
d of side CB is 10
Angela's use of the Pythagorean Theorem of 10²+6²+c² is incorrect; she put the right values in the wrong spots, the formula needed is:
6²+10²=c²
Option C- Angelica's side lengths were too long.
S = 2*(6.72*12.7 + 5.78*(6.72 +12.7))
.. = 2*(85.344 +5.78*19.42)
.. = 2*197.5916)
.. = 395.1832
The surface area is about 395.2 cm^2.
