Hey there :)
27x² is what we are trying to factorise
When factorising, we do not add but we multiply
Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²
Yasmin is right
For this case we must simplify the following expression:

We solve the parenthesis:

We apply distributive property to the terms within parentheses:

We add similar terms:

Recursive Formula--
It is the formula which is used to represent the nth term of a sequence in terms of (n-1)th term of the sequence.
Here we are given a table of values by:
n f(n)
1 4
2 20
3 100
i.e. when n=1 we have:

Also,

Also,

Hence, the recursive formula is:

The answer is -7 because when you minus a negative number you add it, and -10 + 3 is -7. I hope this helps!
Answer:
10
Step-by-step explanation:
given

we first need to simplify the expression before we find it's value when s=-3
positive times negative=negative
so the equation becomes

substituting s=-3 into the equation.

=

=the negatives cancel out leaving
