Answer:
phil collins in the air tonight
Step-by-step explanation:
b = -0.5
4 + 2 = - 0.5 * 4 + 8
6 = -2 + 8
6 = 6
Which is true, Therefore the answer is -0.5
Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.
6 squares * 8 rows = 48
1/2 of the squares are blue so 48 divided by 2= 24
you can also do it this way 6 squares in a row 1/2 are blue so 3 are blue
3 blue squares * 8 rows = 24 blue squares
