Answer:
49n² - 70n + 25
Step-by-step explanation:
Area of a square = s²
Where,
s = side length = 7n - 5
Area of the square = (7n - 5)²
= (7n - 5)(7n - 5)
= 7n(7n - 5) -5(7n - 5)
= 49n² - 35n - 35n + 25 (distributive property of equality)
Add like terms
Area = 49n² - 70n + 25

So look at the patterns.
How much bigger is 15 to 3?
Answer = 5x bigger.
What is 5x smaller than 40? (in other words, 5 x ? = 40)
Answer = 8!
So, the missing 'x' = 8
Answer:
2x^5 + 7x^3 - 5x^2 + 4x^3
Simplify:
2x^5 + 11x^3 - 5x^2
