Answer:
480 inches squared
Step-by-step explanation:
The formula for the area of a rhombus is pq/2, where p and q are the diagonals. In the picture, half of a diagonal is 10 (which I am assuming 10 does not represent the whole diagonal), so all of the horizontal diagonal is 20.
Applying the Pythagorean Theorem to this, we get 10^2 + x^2 = 26^2. After simplifying, this becomes 100 + x^2 = 676, and therefore x = 24. Multiply this by 2 to get the full vertical diagonal, the area is simply 48*20/2 which is 480 inches squared.

Answer:
-136
Step-by-step explanation:
This series can be written as: (14 - 3*0) + (14 - 3*1) +...+ (14 - 3*n)
The sum of the first 16 terms is:
14*16 <u>- 0 - 3 - 6 - 9 -...</u> = 224 - 360 = -136
This underlined bit can be calculated in many ways, I personally used my calculator, but there are formulas to do so.
