Answer:
a=1
Step-by-step explanation:
Because x-1 is factor of f(x)
for x1=1, f(1)=0, then
f(1)=5*1^3+a*1^2-4*1-2=0
5*1+a*1-4-2=0
5+a-6=0
a-1=0
a=1
Firstly you would do 30 - 10 = 20, so their ages combined is 20, Laura has to be 15, and Luci has to be 5.
Second, 4 years ago, Peter was 15 and Sylvia was 5, and also in 5 years Sylvia will be 14 and Peter will be 24.
Hope this helps.
