Answer:
Tristan's sister was eat 4/15 of the strawberries.
Step-by-step explanation:
2/3:1=x:2/5
2/3×2/5=x
x=4/15
1
let's find the zeros of the divisor
x+2=0
x=-2
let x²-3x+2k =f(x)
Now f(-2)=(-2)²-3(-2)+2k=7
4+6+2k=7
2k=7-10
2k=-3
k=-3/2
This is an expression
This means that there is no answer, n+6 is as is until given more information
