Step-by-step explanation:
Linear functions are in the form y=mx+b.
But the functions are in the form of y=x^4 and y-x^2=4.5.
Their exponents make them a quadratic function so it doesn't have the same rate of change. Therefore the equations are not linear. They are quadratic.
36/12=3 Which give you the enlargement of the smaller triangle to the bigger one.
You work out the missing side by putting it into an equation:
3(x-10)=39
Then solve it.
First expand the brackets:
3x-30=39
The rearrange to get x on its own and that will be your answer:
3x=39+30
3x=69
x=69/3
x=23
Answer: 5
