Which of these could be a step to prove that BC^2 = AB^2 + AC^2? Options:
1. By distrubtion, AC^2 plus AB^2 = BC multiplied by the quantity DC plus AB.

2. By distrubtion, AC^2 plus AB^2 = BC multiplied by the quantity DC plus BD.

3. By distrubtion, AC^2 plus AD^2 = BC multiplied by the quantity DC plus AB.

4. By distrubtion, AC^2 plus AD^2 = BC multiplied by the quantity DC plus BD.

answer: the value of x is 7cm

step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
