Hello!
If Nia is three years older than half of Jordan's age, we must divide Jordan's age by 2 (to find half of his age).
Jordan is eight years old:
8 divided by 2 equals 4
4 years old is half of Jordan's age. Now, to find Nia's age, we must add 3 to half of Jordan's age (4).
4+3= 7
Nia is 7 years old.
I hope this helps answer your question! Have a great day!
121 just add the other two angles
Answer:
f(x) = -x^2 + x + 13 find f(9) = -59
Hope this helps :)
Answer:
Step-by-step explanation:
From the figure attached,
If the figures shown are congruent (Equal in shape and size), length of all the sides must be equal.
Therefore, sides sides CD and GH must be equal in measures.
Distance between the two points
and
is given by,
d = 
Length of the side CD having ends C(-4, 4) and D(0, 5) will be,
CD = 
CD = 
= 
Length of GH having ends G(0, -4) and H(4, -5) will be,
GH = 
= 
= 
Therefore, m(CD) = m(GH)
Similarly, we can prove all corresponding sides of two figures equal in measure.
This shows ABCD ≅ EFGH.
