Answer:
Kyrie score = 25
Steph score = 30
Step-by-step explanation:
Given that
In a basketball game, Kyrie scored 5 less than twice as many as Steph. Combined the two scored 55 points.
Let us assume Kyrie score as x.
Combined score = 55
Hence Steph's score = 55-x
Also given that Kyrie scored 5 less than Steph
So
Add x to both sides
Hence answer would be
Kyrie score = 25
Steph score = 30
Verify:
combined score = 25+30 =55
and 30 = 25+5
Verified

Answer:
C
Step-by-step explanation:
When completing the square, we essentially want to create a perfect square trinomial by adding a constant.
If we have the following expression:
And we want to complete the square, we will need to divide the b-coefficient by half and then square it.
Thus, the added term should be:
In the given equation, we have:
The b term here is 8. Therefore:
The value we would add would be 16.
The answer is C.
Further notes:
To complete the square, add 16 like mentioned earlier. However, we also need to subtract 16 to balance things out:
The expression inside the parentheses is now a perfect square trinomial. Factor it:
And we are done!
