8) A rectangle's length to width ratio is 9:4. If its length is 14 cm more than its width, what is its area?

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

answer: 414,377,008

step-by-step explanation:

just multiply it

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:
