Answer:
Associative property of addition
Answer:
a = 6
Step-by-step explanation:
Answer:
x² + 1
or if we suppose
x² + 1 = 0 the n we get value of x
x = ±1
Step-by-step explanation:
x²+x/x (cancel out both x/x we get)
x² + 1
Let suppose
x²+x/x = 0
x² + 1 =0
x²=-1
taking square root on both side we get
x = ±1

Answer:
2 small notebooks and 4 large notebooks
Step-by-step explanation:
$8 × 2 = $16
$10 × 4 = $40
2 + 4 = 6
$40 + $16 = $56
Hope that helps.
collect the like terms
4x - 9 = 6-x
4x + x= 6+9
and then complete the equation
5x = 6 + 9
5x = 15
x = 15 ÷ 5
x = 3
