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
I'll try to do each individual step, hopefully that'll clear it up
w= 3(2a+b)-4
w+4= 3(2a+b)
(w+4)/3 = 2a+ b
2a= ((w+4)/3) - b
a= (((w+4)/3) - b)/ 2
Hiiiiiiiiiiiii
The value of x is 1 & y is 2 (a).

Step-by-step explanation:
we know that product do extreme is equal to the product of means
105:280::x:8
105*8=280x
840=280x
x=840/280
x=3
