Answer:
384 cm²
Step-by-step explanation:
Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.
Area of a triangular face
= ½ ×12 ×10
= 60 cm²
Base area of pyramid
= 12 ×12
= 144 cm²
∴ Surface area of pyramid
= 4(60) +144
= 240 +144
= 384 cm²
Answer: 26
2³ + 4(2 + x) for x = 10
- first do 4(2 + x) which is
8+4x
- Evaluate 2 cubed
You get 2 times 2 times 2.
That would get 8
Our expression is 8 + 8+x
x = 10
Substitute the values.
It is Now eight plus 8 plus ten
So when you Calculate eight plus 8 plus 10
You will get 26

The value decreases $187.5 a year, hope it helps, please let me know if im right
We have
The rational root theorem suggests that other possible roots may be -6, 6, -3, 3, -2, 2, -1, and 1. It turns out that 
is a root, since 
, so 
is also a factor and we have
Finally, we can factorize the remaining quotient easily:
so the other factors are , 
, and 
.
