Answer:
Assuming you wanted to find that mystery number:
It would be 5.75.
Step-by-step explanation:
5 = 4x - 18
Add 18 to both sides of the equation:
5 + 18 = 4x - 18 + 18
23 = 4x - 18 + 18
23 = 4x
Divide each side by 4:
(23/4) = (4x/4)
23/4 = x
5.75 = x
x = 5.75
I think the mathematical equation for this sentence is
<em>(Step 1)</em>
4x-18=5 Add 18 to both sides to get the numbers on the same
+18 | +18 Side of the equals sign.
----------------------
4x =23
<em>(Step 2)</em>
4x =23 / 4 Divide equation by four
x=5.75 The answer is X=5.75
Hope I was able to help :)

Answer:
3z(2x - 3)
Step-by-step explanation:
Area of a rectangle, a = height * width
height, h = 3z

expand
a = 6xz - 9z
a = 3z(2x - 3)
