25
Step-by-step explanation:
Answer:
D = 9.4868
Step-by-step explanation:
The expression is the following
D = √((x2-x1)^2+(y2-y1)^2)
Where
(x1,y1) = (4,6)
(x2,y2) = (7,-3)
D = √((7-4)^2+(-3-6)^2)
D = √((3)^2+(-9)^2)
D = √(9+81)
D = √(90)
D = 9.4868
Answer:

Step-by-step explanation:
we know that
The standard form of the quadratic equation is equal to
we have

eliminate the parenthesis

group terms that contain the same variable

combine like terms

For #6 I think it's 90+90+90*1/2.
