Step-by-step explanation:
y=x(x+3)-1(x+3)
y= x^2+3x-x-3
y=x^2+2x-3
that is the answer
Answer:
Peter is 20 now
Step-by-step explanation:
Now
P = A +5 and J = 2P
plug in P in J = 2P = 2(A+5) =2A +10
In 5 years
J+5 = 3A
2A+10+5 = 3A
2A + 15 = 3A subtract 2A from each side
A = 15 so Alice is 15 now
P = A+5 =15+5= 20 so Peter is 20 now
Let's check :
P=20 J=40 A=15
in 5 years J = 45 A =3*15=45

Answer:
17>x>0
Step-by-step explanation:
-9<-x+8<8 (equation)
-17<-x<0 (subtract 8 from all parts)
17>x>0 (multiply all by -1)
His claim is reasonable because 154÷25 6.16
6.16×2= 12.32 so it would be 12 dollars off!
