My book is 131 pages. i have been reading 7 pages each day for 8 days. how many pages are left to read?

75

Step-by-step explanation:

7x8=56

131-56=75

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
