What are the roots of the equation (p2-q2)x2 - (q2-r2)x + (r2-p2) = 0

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

the answer is simply just 6n add the two together as they have an n

the photograph is photographer and- in the process- ourselves.

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
