Answer:
the answer is the first one!
because if x=-3 we know that |x|=|-3|=3
For the given sequence we have the formula:
Sₙ = 1 + (n - 1)*2
The 50th square will have 99 shaded squares.
<h3 /><h3>
How many shaded squares are on the n-th square?</h3>
Here we have a sequence:
The first square has 1 shaded squares.
the second square has 3 shaded squares.
The third square has 5 shaded squares.
And so on.
Already you can see a pattern here, each next step we add 2 shaded squares, then we can write the formula:
Sₙ = 1 + (n - 1)*2
Where S is the number of shaded squares and n is the number of the figure.
Then the 50th square will have:
S₅₀ = 1+ (50 - 1)*2 1 + 49*2 = 99

Answer:
-5x-8-11y
Step-by-step
Because you shift 10x to -10x and then 5x-10x = -5x
You leave the -8 the same
You do 3y to -3y and then do -3y -8y = -11y
Hence altogether you get, -5x -8 -11y
