Answer:


Step-by-step explanation:
From the question we are told that
Sides difference 
Area difference 
Let first square be A
Let second square be B
Generally the area of a square is mathematically given by
Area of a square
Area of a square

Therefore from the equations above




Therefore

Answer:
Step-by-step explanation:
I think you mean a^2 + 16a + 64.
The x-intercepts are the values of a for which the polynomial equals zero.
a^2 + 16a + 64 = (a+8)^2 = 0
a = 8
The x-intercept is 8.
Answer:
-2x^{2}-12x-26
Step-by-step explanation:
(x+3)^2 = x^2+6x+9
-2(x^2+6x+9)-8
-2x^2-12x-18-8
-2x^2-12x-26
Answer:
D $1298
Step-by-step explanation:
10% of 5200 is 520
1% is 52
0.5% is 26
