If I understand your question well, I suppose you mean
These are linear equations that can be solved simultaneously;
5m+3n=41
3m-6n=9 (multiplying the first equation by 3 and the second by 5)
15m+9n=123
15m-30n= 45 (subtracting the two equations)
39n = 78
n = 2,
and for m, 3m = 9+6(2)
= 21
m = 7
Therefore, n=2 and m=7
202 ft^2
The lateral area is the area of all the sides except the base. So you find the area of the triangles (16), then the left rectangle (80), then the right rectangle (90). Finally you add them together.
16+16+80+90=202
Answer:
He spends 36$
Step-by-step explanation:
Multiply 3.00 by 12 months. You will get 36.00 Hope this helps, let me know if correct, and have a great day!!
180(n-2)
N is number of sides
Nonagon has 9 sides.
9-2=7
7x180=1260
