If two positive integers p and q are written as p = a^3b and q = ab^3, a and b are prime number , then HCF ( p, q) is

b. x + 1

step-by-step explanation:

i'am smart

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.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

sorry not knowing about that
