Find values of a and b that make the following equality into identity:

1.

2.

Step-by-step explanation:

1. Given:

To find a and b, add two fractions in right side:

So,

Two fractions with same denominators are equal when they have equal numerators, so

Equate coefficients:

From the second equation:

Substitute it into the first equation:

Hence,

2. Given:

Note that

To find a and b, add two fractions in right side:

So,

Two fractions with same denominators are equal when they have equal numerators, so

Equate coefficients:

From the first equation:

Substitute it into the second equation:

Hence,

the answer is c hope it

step-by-step explanation:

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
