Step-by-step explanation:
You have to apply the area of triangle formula :





The answer for is a) x=12
The center is (2,-1) and the radius is 3
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
