Match each equivalent expression with the property that it represents.
OlgaM077 [116]

Answer:

Associative Property of Multiplication

[ 3(5) (4) = (3) 5(4)]

Identity Property of Multiplication

5(1) = 5

Identity Property of Addition

(3 + 5) + 0 = (3+5)

Commutative Property of Addition

3 + 5 = 5 + 3

Associative Property of Addition

3 + (5 + 7) = (3 + 5) + 7  

​

Step-by-step explanation:

The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.

The identity property of 1 says that any number multiplied by 1 keeps its identity.

(1-w-w²)⁶=64 prove thta​
VLD [36.1K]

1−w−w2=64

Step 1: Simplify both sides of the equation.

−w2−w+1=64

Step 2: Subtract 64 from both sides.

−w2−w+1−64=64−64

−w2−w−63=0

For this equation: a=-1, b=-1, c=-63

−1w2+−1w+−63=0

Step 3: Use quadratic formula with a=-1, b=-1, c=-63.

w= −b±√b2−4ac /2a

w= −(−1)±√(−1)2−4(−1)(−63) /2(−1)

w= 1±√−251/ −2
