<h3>Answer:   0</h3>

=================================================

Explanation:

Think of z as having 1 zebra

2z means we have 2 zebras

If we started with 2z, and subtracted off 2z, then we're left with 0 zebras. We write this as 0z or just 0 since 0 times anything is 0.

---------

As another example:

Let's say we wanted to simplify 5z - 2z

Well that's the same as saying "5 zebras take away 2 zebras". We'd be left with 3 zebras because 5-2 = 3

Since 5-2 = 3, this leads to 5z-2z = 3z. The difference is that I tacked 'z's onto each number.

What is 2(3a+2b-7) equivalent too?
zloy xaker [14]

Answer:

6a+4b-14

Step-by-step explanation:

For this, we have to use the distributive property.

This means we multiply each value in the parentheses by 2.

2*3a=6a

2*2b=4b

2*(-7)=-14

So our equation is:

6a+4b-14

Write a polynomial function with the zeros 1, -2i
Helga [31]
F( x ) = ( x - 1 ) ( x + 2i )( x - 2i ), because the zeroes are 1, -2i, +2i ;
f( x ) = ( x - 1 )( x^2 - 4i^2 ) = ( x - 1 )( x^2 + 4 ) = x^3  - x^2 + 4x - 4 ;
