Answer:
<h2>168 ft²</h2>
Step-by-step explanation:
the surface area of the triangular prism =
2×(the base’s area) + the lateral area
the base’s area =
the lateral area =
9×(6 + 5 + 5) = 9×16 = 9×16 = 144
finally,
the surface area of the triangular prism = 24 + 144 = 168

It depends on what you are trying to calculate but the most common way I go to find percentage is to multiply by the number in decimal for ie. 50% = .5.
If you are looking for a way to do it quickly in your head I always take find out what 10% is like in the case of 100 it would be 10 so if I want to find 15% I know I can find 10% and if I cut what 10% is in half I will find 5% so likewise if I add what 10%+5% I will end up with 15%. For example, 10% of 100 is 10 half of 10 is 5 and 10+5 equals 15. If you need to find something like 20% or 30% I know that I can find 10% and instead of dividing(cutting it in half) I can multiply by 2 or 3. 10% + 10% =20%
I hope it helps, if you have more questions let me know!
Answer: c = -5, -8
Step-by-step explanation:
c^2 +13c+40=0
(c+5)(c+8)=40
c = -5, -8
It may be can be number 1 (a)
Answer:

,,,,lol hope it helps i don't know how to explain,,, I guess its just dividing you know like 15÷5= 3 so on
