Yes.
Step-by-step explanation:
The answer to your question is 4×7=28
Answer:
(3, 12)
Step-by-step explanation:
The difference in x between the two points is -1, and the difference in y is 9. To find the other endpoint, add these differences to the midpoint.
4 + (-1) = 3
3 + 9 = 12
(3, 12)
Answer:
EF = 
Step-by-step explanation:
Since this triangle is right, we can use the pythagorean theorem to find the missing side length. The pythagorean theorem states that the square of the hypotenuse(DE) is equal to the sum of the squares on the legs(DF, EF). We can write:
DE^2 = DF^2 + EF^2
and substitute the values:
17^2 = 13^3 + EF^2
289 = 169 + EF^2
EF^2 = 120
EF =
