Find the distance between the given points (2,8) and (7,7)
Ray Of Light [21]

Answer:

d=\sqrt{26}\approx5.0990

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula.

The distance formula is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

d=\sqrt{(7-2)^2+(7-8)^2}

Simplify:

d=\sqrt{5^2+(-1)^2}

Square:

d=\sqrt{25+1}

Add:

d=\sqrt{26}\approx5.0990

And that's our answer :)

What is the GCF OF -20v-50
pantera1 [17]

Answer:

The GCF is -10

Step-by-step explanation:

-10 in the highest/largest number that goes into both -20 and -50.

if you have to factor -20v-50 as well it would be:

-10(2v+5)

and to check if that answer is correct, distribute -10 inside the parenthesses:

-10 times 2v = -20v

-10 times 5 = -50

-20v-50
