Answer:
2√137
Step-by-step explanation:
To find AB, we can use the Pythagorean Theorem (a² + b² = c²). In this case, a = 22, b = 8 and we're solving for c, therefore:
22² + 8² = c²
484 + 64 = c²
548 = c²
c = ± √548 = ± 2√137
c = -2√137 is an extraneous solution because the length of a side of a triangle cannot be negative, therefore, the answer is 2√137.
Answer:
A) 6
Step-by-step explanation:
The ratio is found by dividing a sequence value by the one before. It is "common" if it is the same for any pair of sequence values.
r = y2/y1 = 36/6 = 6
The common ratio is 6.
Answer:
A is correct. (you chose correctly)
Step-by-step explanation:
Parallel lines always have the same slope, so we know it's either a or b because the both have the slope of 1/4. When you plug -1, 5 into the equation you chose, you get 0=0, so that is the correct one.
