x=145°
Step-by-step explanation:
180 = 35 + x
x = 180-35
x= 145°
Mass, hardness, density, luster
Answer:
f(f(x)) = x⁴ + 2x² + 2
Step-by-step explanation:
if f(x) = x² + 1, then f(f(x)) is equal to:
f(x)² + 1
= (x² + 1)² + 1
= x⁴ + 2x² + 1 + 1
= x⁴ + 2x² + 2
Answer:
You could multiply 21*21=441 if its a square
Step-by-step explanation:
Let x = larger odd integer
then (x-2) is the smaller odd integer
Translate:
"sum of two consecutive odd integers is 80" means (x-2) + x = 80
2x -2 - 80
2x = 82
x = 41
