Question

Henry wrote 4z2 - 22 as
4. Are 4z2 – 22 and 4 equivalent expressions?
Explain.

Answer 1

No, 4z^2 - 22 and 4 are not equivalent expressions because 4z^2 - 22 can be factored as 2(2z^2 - 11).

Step-by-step explanation:

No, 4z^2 - 22 and 4 are not equivalent expressions. Let's take a closer look:

The expression 4z^2 - 22 can be simplified further, while 4 is already in its simplest form.

4z^2 - 22 can be factored as 2(2z^2 - 11). This means that 4z^2 - 22 can be written as 2 multiplied by the expression (2z^2 - 11).

Therefore, 4z^2 - 22 and 4 are not equivalent expressions because 4z^2 - 22 has an extra factor of 2 in front of it.

Answer 2

If the q is: are 4z2-22 and 4 equivalent expressions, the answer is No.
4z2-22=4
8z-22 is not equal to 4
If you are looking for value of z, then:
8z-22=4
8z=4+22
8z=26
z=26/8
z=13/4
In case in which z=13/4, than expression
4z2-22 would be equivalent to 4.
Hope this helped.
