(2x+1)=Jeremy´s age
(2x+3)=Sam´s age.
we suggest this equation:
(2x+1)(2x+3)=783
4x²+6x+2x+3=783
4x²+8x-780=0
x²+2x-195=0
We solve this quadratic equation:
x=[-2⁺₋√(4-4*1*(-195))]/2=(-2⁺₋28)/2
x₁=(-2-28)/2=-15 this solution is not valid.
x₂=(-2+28)/2=13
Jeremy´s age=2x+1=2*13+1=27
Sam´s age=2x+3=2*13+3=29

Answer:
The equation would be x^2 + y^2 = r^2
Step-by-step explanation:
This is the base form of any circle. In this case, you would need the value of the radius to finish the equation.
It's a parallelogram, opposite sides congruent.
6x - 7 = 2x + 9
4x = 16
x = 4
12 = y + 3
9 = y
Answer: x=4, y=9
