Answer:
Step-by-step explanation:
f(x)=x²+2
a.
f(a)=a²+2+2=a²+4
b.
f(a+2)=(a+2)²+2=a²+4a+4+2=a²+4a+6
c.
f(c+d)=(c+d)²+2=c²+d²+2cd+2
Answer:
x = 
x = -1
Step-by-step explanation:
The given equation is,
-2(bx - 5) = 16
Dividing by (-2) on both sides of the equation,

(bx - 5) = -8
By adding 5 on both the sides of the equation,
(bx - 5) + 5 = -8 + 5
bx = -3
Dividing by 'b' on both the sides of the equation,

x = 
If b = 3,
x = 
x = -1
A = (100/20)*8
B = (100/32)*8
C = ?
