Answer:
it is 40
Step-by-step explanation:
Factoring:
your equation: x^-4xy+3y^
now figure out what adds to -4 and multiplied to +3 (-3&-1)
use that information to factor.
you get: (x-3y)(x-y)
now use the distributive property to make sure it's the right answer: x^-xy-3xy+3y^
this means (x-3y)(x-y) is correct.
hope this helped :)
Answer:
x = 54
Step-by-step explanation:
These angles are complementary because they add up to 90:
x - 7 + 43 = 90
x + 36 = 90
x = 90 - 36
x = 54
