Answer:
Step-by-step explanation:
the slope is 7/2
the formula is y1-y2 divided by x1-x2.
-11-(-4)=-7
-5-(-3)=-2
-7 divided by -2 equals 7/2
Answer:
BC=3root7
CD=root58
Step-by-step explanation:
According to Pythagorean theorem, in a right triangle,a^2+b^2=c^2. a, b are two legs of right triangle. Cis the hypotenuse
12^2-9^2=63
BC=root63=3root7
BD^2-BC^2=CD^2
121-63=CD^2
CD=root58
