Answer:
So if you have an angle that is 20 degrees, then the complement angle measures 70 degrees.
36x^2+60x+25=(12x+5)(3x+5)
Answer:
a= -12 and b=36
Step-by-step explanation:
a+b=24 and 3a+b
a-3a+b=24
-2a+b-b=24
-2a/-2=24/-2
a= -12
then substitute the value of a in a+b=24 to get the value of b
so let see -12+b=24
b=24+12
b=36
we can check it by the equation -2a+b-b=24
-2(-12)+36-36=24
24=24 so as you have seen the answer is correct
thanks!!!
