Use the Pythagorean Theorem to check out these possibilities (which you really do need to share here).
Note that 13^2 = 12^2 + 5^2, so 12 and 5 are a possible set of side lengths here.
Answer:
It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2
Step-by-step explanation:
B=5 units that is the answer
Use formula: an = a1 * r^(n-1)
a1 = 2, r = -2
a12 = 2 * -2^(12-1)
a12 = 2 * -2^11
a12 = 2 * -2048
a12 = -4096
Solution: -4096
The answer would be 49 + 42b if you multiply 7*7 and 7*6b
