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.

we have this equation:
-52(x-14)=x+3
we solve this equation:
-52x+728=x+3
-52x-x=3-728
-53x=-725
x=-725/-53=725/53 ≈13,68
Solution: 725/53
To check:
the difference between 725/53 and 14=725/53 - 14=(725-742)/53=-17/53
-52 times the diference is= -52(-17/53)=884/53
The number plus 3=725/53 + 3=(725+159)/53=884/53
Using the relative frequency concept, it is found that:
- The number in the highlighted cell is: b. the revenue from sales of convertibles by Pluto Cars
- The relative frequency of this vehicle category compared with the total sales revenue of Pluto Cars is: b. 0.225.
<h3>What is a relative frequency?</h3>
A relative frequency is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The number in the cell has bounds conversible and Pluto Cars, and the table represents the amount earned, that is, revenue, hence option b is correct.
The total revenue of Pluto Cars is of $80 million, with convertibles corresponding to $18 million, hence the relative frequency is given by:
r = 18/80 = 0.225.
