8 0

Answer:

14 days

Step-by-step explanation:

Total Problems = 175

Finished Problems = 8

Remaining = 175 - 8 = 167

8 problems in 30 minutes, means:

30/8 = 15/4 = 3.75 minutes per problem

If he works for 45 minutes, at that rate, he can solve:

45/3.75 = 12 problems per day

To finish 167 problems, he will need:

167/12 = 13.91

Rounded, that is <u>14 days more to finish</u>

Solve for x^2-2x+1=0

seraphim [82]

Answer:

$x=1$

Step-by-step explanation:

$x^2-2x+1=0\\$

We will start by using the quadratic formula.

$\frac{-(-2)+-\sqrt{(-2)^2-4(1)(1)}}{2(1)}$

We will simplify that and get:

$\frac{-(-2)}{2(1)}$

So our answers would be:

$x=1$
