Answer:

B. 3

Step-by-step explanation:

Since you are given that chord AB's length is 8 and is bisected by segment XC, that means segment BC's length is 4 and ∠XCB is a right angle. From there, we use Pythagorean Theorem to solve for length XC:

4² + b² = 5² (Or remember 3-4-5 makes a Pythagorean triple)

c = √(5²-4²)

c = 3

Answer:

not necessarily

Step-by-step explanation:

Taking the square root of both sides, you have ...

±a = ±b

Those four cases resolve to two unique cases:

a = ±b

The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.

zavuch27 [327]

Answer:

$\frac{13}{20}$

Step-by-step explanation:

$\frac{1}{4} + \frac{2}{5}$

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.

$\frac{ 1 \times 5}{4 \times 5} + \frac{2 \times 4}{5 \times 4}$

$\frac{5}{20} + \frac{8}{20}$

$= \frac{13}{20}$

demoninator now doesn't change unless you're multiplying or dividing.
