Answer:
x + y
Step-by-step explanation:
An expression for the average of x,2x and 3y
average = (x+2x+3y)/3
= (3x+3y)/3
= 3(x+y)/3
= x + y
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
