Answer: 14.73
Step-by-step explanation:
The given triangle is a right angle triangle.
EF^2 + DF^2 = ED^2
The hypotenuse is |ED| while the two shorter legs are |EF| and |DF|.
We can then apply the Pythagoras Theorem to find the length of EF.
(EF)^2 + (DF)^2 = (ED)^2
(EF)^2 + (12)^2 = (19)^2
(EF)^2 + 144 = 361
(EF)^2 = 361 - 144
(EF)^2 = 217
EF = 14.73
Hello!
You can break this down
If she added 8 to the number
x + 8
Multiplied the sum by 2
2(x + 8)
it would equal 6
2(x + 8) = 6
The answer is B
Hope this helps!
Answer: the second one i may be wrong but i can relate to you ❤
Answer:
n>-5
Step-by-step explanation:
We have to distribute the -7 first, so:
-105<-7(5-2n) becomes:
-105<-35+14n
To find n, we have to add 35, so:
-105<-35+14n
+35 +35
We get 14n>-70. Now, we have to divide each side by 14 to find n.
14n/14>-70/14.
So, the solution becomes n>-5.
