Answer:
(2,7)
Step-by-step explanation:
We know that the change in x from A to M is -2, and the change in y is 1 -- we can simply double that and add that to A to get B, as M is halfway between A and B. Thus, (6,5)+(-4,2)=(2,7) as the coordinates of B
Answer:
y= -2/3x+7
Step-by-step explanation:
c = √(a² + b²) is the formula for Pythagorean Theorem so you substitute 7 and 3 in for a and b. then solve for c. Which is about 7.62 for the side length
Answer:
x²+y²+z²+2xy-2yz-2zx
Step-by-step explanation:
{(x+y)-z}^2
=(x+y)²-2(x+y)z+z²
=x²+2xy+y²-2zx-2yz+z²
=x²+y²+z²+2xy-2yz-2zx
