Answer:
390 ft^2
Step-by-step explanation:
We will break this shape into two rectangles, one that is 7 ft wide by 30 ft long
and the other that is 25ft-7ft wide by 30ft -20 ft long (18 ft by 10 ft)
1st: 7 ft by 30 ft
A = l*w = 7*30 = 210 ft^2
2nd: 18 ft by 10 ft
A = l*w = 18 * 10 = 180 ft^2
Add the areas together
210+180 = 390 ft^2
Answer:
the answer is n=3
Step-by-step explanation:
If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.
For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x
1: 8 faces and 9 with the base 9 vertices and 16 edges
2: 3 faces and 5 with the bases 6 vertices and 9 edges
3: 3 faces and 4 with the base 4 vertices and 6 edges
Hope this can help you.
Answer:
18a-12b+6c
Step-by-step explanation:
We have got 6 common in this factor 6(3a-2b+c)
So,in order to expand it we just need to multiply 6 with the everything in the bracket..
6×3a=18a
6×2b=12b
6×c=6c
If we arrange the factor after multiplying,then it stands like this 18a-12b+6c...
