4x - 12
Step-by-step explanation:
Expand 8 - 4(-x + 5) as follows:
8 + 4x - 20
4x - 12 (First answer is the correct one)
He makes $400 as an investment because 1400*2= 2800
1200*2= 2400
Subtract the two number 2800-2400= 400
Answer:
<h3>The answer is 54.2 miles</h3>
Step-by-step explanation:
In order to solve this question we use ratio and proportion
From the question
In 25 days geese fly 1355 miles
So we have
if in 25 days they fly 1355 miles
Then in one day they will fly
We have the final answer as
<h3>54.2 miles</h3>

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
