Prove z + z + z + z = 4z. Replace each step with the correct equivalent expression based on the given property or operation. Dra

Olenka [21]

Answer:

Step 1: $z*1+z*1+z*1+z*1=$

Step 2: $z(1+1+1+1)=$

Step 3: $z*4=$

Step 4: $z*4 = 4z$

Step-by-step explanation:

Given

$z+z+z+z = 4z$

Required

Match the steps with equivalent properties

Step 1: Multiplicative Identity Property

This states that:

$x = 1 * x$

So, the expression becomes:

$z*1+z*1+z*1+z*1=$

Step 2: Distributive Property

This states that:

$ab + bc = b(a+c)$

So, the expression becomes

$z*1+z*1+z*1+z*1=$

$z(1+1+1+1)=$

Step 3: Addition

Here, we simply add the expressions in the bracket

$z(1+1+1+1)=$

$z(4) =$

$z*4=$

Step 4: Commutative Property of Multiplication

This states that:

$ab=ba$

So, we have:

$z*4=$

$z*4 = 4*z$

$z*4 = 4z$

The fence is 26*7=182 square feet. 1 gallon is enough for 350 square feet and x for 182 square feet. => x=182/350=0.52 gallons. I hope I'm right.
