(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:
no complex zeros.
Step-by-step explanation:
The given equation is

To find the zeros equate y=0.

We know that, if n>0, then

So,

It means zero or root of the given equation is 0 with multiplicity 5.
Therefore, the given equation have no complex zeros.
Reflection involves mirroring a point over a line.
<em>When L is reflected across the x and y axes, the new coordinates are (7,3)</em>
Given that:

When a point is reflected across the x-axis, the rule is:

So, we have:

When a point is reflected across the y-axis, the rule is:

So, we have:

Hence, the new coordinates of L are (7,3)

Ok so to find this we need to find 25% of 8 and then add that number to 8 itself. SO .25*8=2. So 2+8=10. So the answer is 10. IF you don't get it just ask and i can try to re explain
