Both equal to y so set equal to each other
4x+4=x²+4
minus 4 both sides
4x=x²
minus 4x both sides
0=x²-4x
factor
0=x(x-4)
set each to zero
0=x
0=x-4
4=x
x=4 and 0
2 solutions
Answer:
xy is equal to 15 Q understood
5 of a number plus 3 of a number
It should be 30.4
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2)
You should end up with -56 + 25.6
Next you add those two numbers and you end up with 30.4.
I hope this helps!
