Given:
Triangle DEF
To find:
The perimeter of triangle DEF.
Solution:
Coordinate of D = (-1, 1)
Coordinate of E = (2, 1)
Coordinate of F = (-1, 4)
Distance formula:

<u>Distance of DE:</u>
Here, 


d = 3 units
<u>Distance of EF:</u>
Here, 



d = 4.2 units
<u>Distance of FD:</u>
Here, 


d = 3 units
Perimeter of ΔDEF = DE + FE + FD
= 3 + 4.2 + 3
= 10.2 units
The perimeter of triangle DEF is 10.2 units.
The numbers 7, 11, 12, 13, 14, 18, 21, 23, 27, and 29 are written on separate cards, and the cards are placed on a table with th

So since there are 10 numbers total, only three positive. so 3/10 is also 30%. Or 30% probability of picking an even.
Answer:

Step-by-step explanation:
Remove perfect squares from under the radicals.

_____
The applicable rules of exponents are ...
(x^a)(x^b) = x^(a+b)
√(a^2) = a . . . . . . . for a > 0
(√a)(√b) = √(ab)
Answer:
B. 1/9 cuz it's just saying y is 1/9 of x
Answer:
It helps you see the equation in "picture" form.
Step-by-step explanation:
When you see the inequality in a graph form, most people can benefit from seeing a different version of the same problem.
