A^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 289 - 225
a^2 = 64
sqrt of 64 = 8
a = 8
x = 8
Answer:
Neither
Step-by-step explanation:
It's neither. The terms do not differ (which means you add the same number to each term) by any constant amount. (Arithmetic)
The terms do not have a common number that you multiply the present term to get the next term. (Geometric)
So this one is neither.
Answer:
40 tokens total
Step-by-step explanation:
2 tokens each time for playing a game
After 4 games: 2*4 = 8 tokens used.
so, 32(that are left) + 8(used) = 40 tokens total

Answer:
372 m²
Step-by-step explanation:
A vertical line down the center of the figure will divide it into two congruent trapezoids, each with bases 13 and 18, and height 12.
The area of one of them is ...
A = 1/2(b1 +b2)h
So, the area of the two of them together is ...
A = (2)(1/2)(b1 +b2)h = (b1 +b2)h
A = (13 m + 18 m)(12 m) = 372 m²
