2cents
Step-by-step explanation:
40/20=2
Answer:306
Step-by-step explanation:
since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.
Answer:
The explicit form for this sequence is 
for all 
.
Step-by-step explanation:
The explicit form of an arithmetic sequence of numbers is given by the formula 
, where 
is the first term of the sequence, 
is the difference between two consecutive terms of the sequence, and .
We know that the first four elements for the arithmetic sequence are 
.
To find the general formula for this problem we only need to calculate in the above formula.
For n=2, we have
if we replace 
and 
and solve for we obtain
Therefore the explicit form is for all .
