Answer:
Teo is 11 years old and Richard is 26 years old.
Step-by-step explanation:
Let R be the age of Richard and T be the age of Teo.
<u><em>First set up the equations:</em></u>
The combined age of Teo and Richard is 37:
R+T=37
Richard is four years old than twice Teo's age:
R=2T+4
<u><em>Then, solve the equations:</em></u>
Substitute (2) to (1) and solve for T:
(2T+4)+T=37
3T=11
T=11
Solve for R using (2):
R=2(11)+4
R=22+4
R=26
810
all you need to do is plug in 12 for a and 7 for p. the you solve it.
8*12=96
7*4=28
96+28+11=135
6(135)=810
It is a cubic function that is down up (the direction of the ends) and has roots at (figure out the roots either 1/2/3)
