An extension of the Pythagorean Theorem results in what is the so-called "distance formula".
d^2=(x2-x1)^2+(y2-y1)^2, in this case you have points (-2,4) and (2,0) so:
d^2=(2--2)^2+(0-4)^2
d^2=4^2+(-4)^2
d^2=16+16
d^2=2*16
d=√32 units
d=√(2*16)
d=4√2 units
d≈5.66 units (to nearest hundredth of a unit)
Answer:
AC would be equal to CB, but you didn't give numbers so that's all you can get from what you said
Step-by-step explanation:
Answer:
24.7 repeated
Step-by-step explanation:
Answer:
Step-by-step explanation:
Group like terms 6y-2y= 2-1-2
When a number goes over the equal sign= positive + changes to negative, vice versa.
So final answer is 4y= -1= -4y
Because 4 is decided by -1
Answer:
x = 142
Step-by-step explanation:
The problem;
Inverse operations;
Now undo the square, by squaring both sides;
Inverse oeprations;
x + 2 = 144
-2 -2
x = 142
