Answer:
c = 64
Step-by-step explanation:
(a-b)² = a² - 2ab + b²
h²- 16h + c
So, 2ab = 16h
2 * h * b = 16h {as a =h}
b= 16h / 2h
b = 8
c = b² = 8*8 = 64
Answer:
non-linear

Answer:
A
Step-by-step explanation:
-19-11 = -19 + (-11)
Subtract 32 to both sides to the equation becomes -5x^2 + 7x + 9 = 0.
To solve this equation, we can use the quadratic formula. The quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √(7^2 - 4(-5)(9)) ] / ( 2(-5) )
x = [ -7 ± √(49 - (-180) ) ] / ( -10 )
x = [ -7 ± √(229) ] / ( -10)
x = [ -7 ± sqrt(229) ] / ( -10 )
x = 7/10 ± -sqrt(229)/10
The answers are 7/10 + sqrt(229)/10 and 7/10 - sqrt(229)/10.
