Answer:
Step-by-step explanation:
Hi there!
This equation is written in the form 
. First, use partial factoring:
For x^2-x, the <em>b</em> value is -1 in 
. To complete the square, take the square of half of 1 and add it in the parentheses as the <em>c</em> value:
However, when adding values to one side of the equation, we must to the same to the other side:
Complete the square:
Move 20 to the other side
I hope this helps!
487 + 310 ≈ 500 + 300 ≈ 800

Answer:
a is 39
b is 57
Step-by-step explanation:
you were given two different expressions to substitute.
the first one is p = 8 and d = 1/7
so we substitute into 5p - 7d
that is 5(8) - 7(1/7)
we get 40 - 1
which if we go ahead to evaluate we get 39
The second one p = 3 and d = -6
so we get 5(3) - 7(-6)
we get 15 - (-42)
if we go ahead to evaluate we get 15 + 42
two negative meeting each other gives you positive.
then it going too be 57
0.16 as a fraction becomes 16/100. This can be simplified to 4/25.
None of those are the right answer, though 1/6 as a decimal is 0.16666666... (the 6s repeat forever) so option C is what they're looking for.
