There are three consecutive odd numbers. If the difference between the product of the last two numbers and the product of the first two numbers is 76, what is the sum of all three consecutive odd numbers?

57

Step-by-step explanation:

Numbers=x,x+2,x+4

(x+4)(x+2)-x(x+2)=76

x^2 + 6 x + 8 - x^2 -2x=76

4x=68

x=17

x+2=19

x+4=21

x+x+2+x+4=17+19+21=57

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
