Answer:
2i^2+18i+7
Step-by-step explanation:
(5i^2+8i+10)-(3i^2-10i+3)
5i^2+8i+10-3i^2+10i-3
2i^2+18i+7

Step-by-step explanation:
A prism is named by the shape of its bases. That makes this an octagonal prism
The shape of the bases are octagons.
The vertices are all the letters
The lateral edges are all the vertical lines connected by the vertices. RQ, WN, VM, are all examples.
The rectangles making up the sides are called lateral faces.
The altitudes are the same as the lateral edges. They all represent the height of the prism.

Step-by-step explanation:......
A total of $27,000 was invested; part of it at 10% and part of it at 12%. The total yield was $2990. How much was invested at each rate?
Let
x -----> amount invested at 10%
(27,000-x) -----> amount invested at 12%
we have that
0.10(x)+0.12(27,000-x)=2990 ------> equation A
solve for x
0.10x+3,240-0.12x=2,990
0.12x-0.10x=3,240-2,990
0.02x=250
x=$12,500
so
27,000-x=27,000-12,500=$14,500
therefore
amount invested at 10% ----> $12,500
amount invested at 12% -----> $14,500
Answer:
B - x=5
Step-by-step explanation:
If y=25 is 250% more than y=10, so multiply 2 by 250% and you get 5
